samsung-manta: update arch to armv7

This updates the architecture for manta as written in the wiki from armhf to armv7. To test it, I built and ran sxmo successfully (if a bit janky).

Update: xfce4 and plasma-desktop also work.
Their (sxmo/xfce4/plasma-desktop) common problem is that they all boot to a black screen. For some reason issuing sudo startx over SSH fixes it for all of them. (even though the command itself fails)

Addendum:

If somebody wants to try it on their own Nexus 10, here's what worked for me. (Because fastboot/heimdall both didn't)

android to pmos:

Installation from recovery
xfce4 and plasma-desktop (and probably others) don't fit into /system, so use pmbootstrap install --android-recovery-zip --recovery-install-partition=data instead.

pmos back to android / in between pmos installations / "oh no, I broke everything"

Get the zip from Google
Unpack the zip
Open a terminal in the folder
./flash-all.sh
Afterwards the tablet tries to boot into android, but it never actually finishes booting because some things are still busted. So, go to the bootloader (hold up+down+power until you see the bootloader), choose recovery mode, unlock the recovery (hold power, tap up, release both), choose wipe data/factory reset, choose Yes -- delete all user data, then choose reboot system now. Everything should be fixed :)

Maybe there is something useful in dmesg?

Can you update the installation instructions in the wiki of the device and put it there?

https://wiki.postmarketos.org/wiki/Google_Nexus_10_(samsung-manta)#Installation

Your "oh no, I broke everything" ( ) section would also be useful for the wiki, and the armhf -> armv7 note can be removed. Mentioning the "startx" issue from above in the wiki would be great as well, you could link to this MR where you described it in detail. (If there's more to discuss on the "startx bug", please create a dedicated issue.)

Patch looks good, thanks @FelixLK!

Wiki edit done.

Thanks @ollieparanoid for the feedback and merge, and thanks @minlexx for marking the move as done :)

I'll investigate the strange black screen problem some more in the next few days, we'll see how it goes!
