[skip ci]: too many packages changed, build won't finish in time.
ollieparanoid made sure that this builds for x86_64,
aarch64, armhf, armv7. Also he tested that this boots up
in qemu-amd64.
Since the Qt upgrade, Plasma Mobile boots into a black screen, even
on the current version in the master branch. Bhushan recommended we
update to the latest plasma framework anyway (which is possible now
due to the newer Qt version) and try to fix it from there. See #159.
[skip ci].
* Add postmarketos-ui-plasma-mobile
* Add more required packages
* Upgrade plasma sources
* Modernize APKBUILDs
* Make it run in general
* Support RGB32 framebuffer with BGR order (thanks @zhuowei!)
