Add option for mainline kernel iso downstream kernel. Note that a lot is
not working yet due to incomplete devicetree, so this is for development
purposes only.
Add sony-fusion3 firmware subpackage to enable wifi.
Enable Qoalcomm Prima WLAN driver and fix wrong path in kernel.
[ci:skip-build] Already built on CI in MR
At the moment we have Contributor: lines on some packages (but not all of them),
but often they don't represent the actual contributors to the package very well.
E.g. when we added them retroactively to the device packages we only added
the initial contributor (which isn't necessarily the person
who made most of the work for a device...)
The Git history is the most representative source for figuring out
who contributed to a package, so there is no reason to duplicate that
into the APKBUILD.
[skip ci]: way too many packages
Prepare for better device categorization by moving everything to testing
subdir first.
[skip-ci]: chicken-egg problem: passing pmaports CI depends on pmbootstrap MR
depends on this MR
