community/firmware-qcom-adreno: new aport (MR 2625)

Add a new firmware-qcom-adreno APKBUILD that packages the GPU firmware
from upstream linux-firmware as separate packages. It is basically
a minimal replacement for linux-firmware-qcom that allows saving rootfs
space by installing only the firmware that is really relevant for the
device.
