[Intel-gfx] [PATCH 05/26] drm/fb-helper: set fbi->fix.id in fill_info()

Looking at the oldest/most popular drivers ${driver}drmfb seems to be
the standard, except i915.ko went with "inteldrmfb". I guess renaming
that for consistency won't hurt, it definitely confused me when I
started with kms 10 years ago.

I hope this never became uapi ... worst case drivers can overwrite it
after having called fill_info().
