Better Mozilla Flame device support
Did some cleanup on the Flame, especially with installing device-specific firmware. Please take a look and let me know if this PR makes sense.
Firmware blobs were copied to an external repository and are loaded from there. This is an alternative to actually linking the blobs from the special partitions (which I mount in fstab anyway, for now).
- No need to append DTB to kernel
- Remove kernel module build for now
- Add device-specific firmware package
- Add special partitions to fstab
- Fix typo in screen width
