drm/vram: Support scanline alignment for dumb buffers
Adding the pitch alignment as an argument to
drm_gem_vram_fill_create_dumb() allows to align scanlines to certain
offsets. A value of 0 disables scanline pitches.
v3:
* only do power-of-2 test if pitch_align given; fails otherwise
* mgag200: call drm_gem_vram_fill_create_dumb() with pitch_align
v2:
* split of patch from related hibmc changes
* test if scanline pitch is power of 2
