Could check the attached three patches?

i915 is the only driver passionate about the header self-contained'ness.
It would not be horrible to implement a own build rule in i915 Makefile.

0003 decreases the amount of code.

0001 and 0002 are trivial and can go in independently.
( I just send them to intel-gfx ML)

Thanks.
