[skip ci]: too many packages have changed

Add firmware required to make WiFi work. Patch the kernel so the ramoops
dmesgs can be read properly without having to remove that header every
time.

This patch fixes Xorg. Adapted from the Xiaomi A1.

USB host mode is useful (essential?) on the devkit for adding a
keyboard/mouse to interact with the desktop since the onboard display
and touchscreen are very much in flux.

This is useful for dumping device registers when mainlining.

[skip ci]: takes longer than 1h to build, ollieparanoid made sure that
           it builds locally.

The LineageOS kernel integrates the Wi-Fi driver, so reconfigure with
the Lineage defconfig and copy the Wi-Fi options over to our defconfig.

This doesn't get Wi-Fi working yet, but it gives a good starting point.

This program allows users to configure Qt5 settings (theme, font, icons,
etc.) under DE/WM without Qt integration.

Otherwise kwin can't register it's services.

Do not replace compiler-gcc.h. This is necessary now, as we are
replacing compiler-gcc.h by default again, as it is needed for most
kernels. Not increasing the pkgrel to avoid unnecessary rebuild, I have
verified that this works.

NOTE: in the last commit message, I wrote about OVERWRITE_GCC=0. But
the variable is called REPLACE_GCC, as I've decided to rename it before
submitting. I forgot to change it in the commit message.

[skip ci]: this kernel takes more than one hour to build, so it won't
           finish in CI.

Instead of never overwriting compiler-gcc.h if it exists, overwrite it
by default except if OVERWRITE_GCCH=0 is set in the environment.

Most kernels *do* need this file replaced and won't build without this
patch.

Adds an initfs-hook to enable touchscreen on motorola-athene.

This modernizes the APKBUILD that was based from outdated one (still
needs GCC6) as requested in !165 (comment 133993271). Also adds a fix
to allow Xorg booting, osk-sdl doesn't work yet as it throws some ugly
faults in kernel related to fbcon.

I made a firmware package APKBUILD based on the motorola-titan and added
it to the device-motorola-cedric APKBUILD.

[skip ci]: build takes pretty long, at least the download timed out
in CI last time. ollieparanoid made sure that this builds before
merging.

At least one newer kernel already includes the compiler support split
stuff, so don't overwrite it if it already exists.

Support generating the aarch64 legacy uboot initrd files, not only the
armhf version. Use deviceinfo_arch to choose the right arch.

Tested on sony-amami with TWRP 3.0.2.

[skip ci]: this compiled in CI before, no need to run again.

The 5.0 kernel now includes -Werror= parameters in the makefile, this
changes downstreamkernel_prepare.sh to support them. Without this, the
script will replace, for example, -Werror=blah with =blah, which causes
the kernel compilation to fail.

[skip ci]: ollieparanoid made sure this builds for x86_64, armhf,
           aarch64, armv7.

Finally got display working, but it's based on MoKee kernel which is
also hosted on GitHub by community. So what works:

* USB Networking
* Flashing
* Touchscreen
* Display
* Weston with Xwayland

The device boots and shows the splash screen properly, after about 3
sec the screen went black. I had to
"echo 127 > /sys/devices/i2c-0/0-0038/leds/lm3530-backlight/brightness"
to make the backlight work, even though the value of it was already
127.

Tested it with Weston and it boots fine.

I have tested this on xfce4 and weston. Also plasma-mobile "works"! The
performance isn't any better than on armhf, it's still less than one
frame per second and llvmpipe still doesn't work.

After switching to armv7, this kernel fails to compile with the
following error unless CONFIG_CRYPTO_AES_ARM_BS is disabled:

arch/arm/crypto/aesbs-core.S:449: Error: thumb conditional instruction should be in IT block -- `addeq r6,r6,#0x10'
arch/arm/crypto/aesbs-core.S:904: Error: thumb conditional instruction should be in IT block -- `addeq r6,r6,#0x10'
arch/arm/crypto/aesbs-core.S:2100: Error: thumb conditional instruction should be in IT block -- `subne r9,#0x10'

We had 2 music players included which doesn't make sense, and vvave is
actually made with a focus on mobile.

[skip ci]: do not try to build this merge request, ollieparanoid made
           sure that it builds for x86_64, armhf, aarch64.

Tested on Qemu amd64. Everything built and ran successfully. Even
better, applications start in full-screen again!

Quite a few Nexus 5X devices have the tendency to bootloop after a while
of being on, iirc because it overheats. This has been a known issue for
quite some time, and most Android ROM's for it have measures in place to
prevent this, in the form of disabling some CPU cores (iirc "Big cores"
or something like that). My Nexus 5X is also subject to this issue.

According to craftyguy, resolving this is as easy as changing the boot
command to not use those CPU cores. This commit does exactly that. It
should probably be made optional for people with this device without
that issue, but since I have no clue how to do that atm, this is the
safest for now.

OTG was tested with a keyboard and a pendrive.

[skip ci]: this was built successfully in CI earlier, only rebased and
           squashed the commits here.

mdss-fb-init-hack fixes the black screen (e.g. in XFCE4)

Initial support for Xiaomi A1 aka xiaomi-tissot using LineageOS 15.1
kernel, has similar board to Xiaomi Redmi 4 aka xiaomi-mido with some
differences that had to be patched such as reversing skip_initramfs and
ignoring dm param. 16.0 kernel boots but display fb init doesn't work.

Weston boots with touch support, SSH via USB RNDIS works.

[skip ci]: this built once in CI already, good to go.

Tested on Qemu amd64. Everything builds and runs correctly.

[skip ci]: ollieparanoid made sure that this builds for x86_64, armhf
           and aarch64.
