Generate DRM/MSM headers on the fly during kernel build. This removes a
need to push register changes to Mesa with the following manual
synchronization step. Existing headers will be removed in the following
commits (split away to ease reviews).

Is this approach common in upstream kernel? Isn't it a bit awkward from
legal perspective to rely on a source file outside of kernel during
compilation?

As long as the source file for that file is available. For examples of
non-trivial generated files see
arch/arm64/include/generated/sysreg-defs.h and
arch/arm64/include/generated/cpucap-defs.h

This change does two things:

1) move adreno folder compilation under "adreno-y", move display related 
files compilation undere "msm-display-y", move common files under "msm-y"

2) changes to generate the header using gen_header.py

Why not split it into two changes?

Are below two changes related to this patch?
