This is needed with the 5.11 kernel. Also adjust the vram & cma sizes
for all msm8974 devices.
The CMA size is 256MB as set in the kernel config.
VRAM is default 16MB although it is set to 192MB with a kernel patch;
but set it manually for all devices to make it possible to remove this
patch in the future - until we have IOMMU working.
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
This device is probably broken at this point, but since we want to
remove linux-postmarketos-mainline/stable it really has best chances
to work (somewhat) on linux-postmarketos-qcom-msm8974.
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
