From: Ville Syrjälä <ville.syrj...@linux.intel.com>
Move intel_fb_xy_to_linear() and intel_add_fb_offsets()
These are technially sitting somewhere between plane vs. fb code,
but we do have a bunch of code like that in intel_fb.c anyway.
Might need to think about splitting intel_fb.c into pure fb vs.
plane->fb related stuff somehow, but dunno if that's even feasible.
