drm/i915: Clean up fbc vs. plane checks
Let's record the information whether a plane can do fbc or not under
struct inte_plane.
v2: Rebase due to i9xx_plane_id
Handle BDW/HSW correctly
v3: Move inte_fbc_init() back since we depend on it happening
even with i915.disable_display, and populate
fbc->possible_framebuffer_bits directly from the
plane init code instead
v4: Add note about plane A being tied to pipe A on HSW+
