xiaomi-santoni: Added support for osk-sdl and improvements

I've added support for osk-sdl to the xiaomi-santoni, it works fine, charging-sdl works fine, but full disk encryption doesn't work yet. Here is charging-sdl running:

Full Disk Encryption barely working on this device. After unlocking, it goes on black screen forever, this is what shown in dmesg:

[   22.148732] device-mapper: table: 252:1: linear: dm-linear: Device lookup famled
Y   22.148767]$device-mapper: ioctl: error adding target to table
[   22.15▒202] device-mapper: table: 252:1▒ linear: dm-linear: Device lookup failed
[   22.558237] device-mapper: ioctl: error adding target to table

pmOS is installed in a SD Card.

The patch looks good as is, and it is already an improvement. If you want, we can merge it already, and you can fix it up further from there on.

Regarding the colors, you would probably need another format than rgba (maybe you can also play with the settings in the kernel and change the mode there?).

Regarding the dm-crypt error: that is a weird one. I found this random patch, which suggests that maybe your kernel might be reporting a "device lookup failed" error instead of a "device busy" error, which it should display instead. Maybe this is helpful - you could check in your kernel's source if that is the case. And regarding debuggging: try to open it manually: https://wiki.postmarketos.org/wiki/Osk-sdl#Unlocking_via_telnet

As always, thanks for your great work @danct12

Not sure if this is intended or not, but charging-sdl still kept the backlight turned on after the battery screen disappears. I suppose that the backlight are supposed to turn off, right?

@danct12 it's not implemented yet, see https://gitlab.com/postmarketOS/charging-sdl/issues/18

@ollieparanoid Should we ignore the p2p0 interface (used for Wi-Fi Direct)? Some people doesn't know and attempted to connect to access point through that interface, which doesn't work.

I've seen you pushing my patch, awesome. Anyway, I'm currently looking into jack detection:

• When headphones are plugged, /sys/devices/virtual/switch/h2w/state changes to 1 and 3, or sometimes 4.
• When nothing is plugged, it changes to 0.

I'll push a patch to @danct12 when I figured out how the jack detection works.

Compare with previous version

This should be alright to be merged now, I'll try to think how to get PulseAudio runs as user on startup in the future.

Changes that I've did with the latest commit:

• Make all applications to use pulseaudio by default, if pulseaudio doesn't exist (not started) then it'll use the sysdefault fallback.
• Disabled tsched due to audio being choppy and glitching (had something to do with the CPU or qcom's DSP)
• Commented kernel spam due to substream runtime not found: [ 3753.419598] msm_pcm_volume_ctl_get substream runtime not found
