drm/i915: Merge of visible and !visible paths for primary planes
Fold intel_pipe_set_base() in the update primary plane path merging
pieces of code that are common to both paths.
Basically the the pin/unpin procedures are the same for both paths
and some checks can also be shared (some of the were moved to the
check() stage)
v2: take Ville's comments:
- remove unnecessary plane check
- move mutex lock to inside the conditional
- make the pin fail message a debug one
- add a fixme for the fastboot hack
- call intel_frontbuffer_flip() after FBC update
v3: take more Ville's comments:
- fold update code under if (intel_crtc->active), and do the
visible/!visible split inside.
- check ret inside the same conditional we assign it
v4: don't use intel_enable_primary_hw_plane(), the primary_enabled
check inside will break page flips
v5: take more Ville's comments:
- set primary_enabled to true and add BDW hack
- unify if (old_fb) and if (old_fb != fb)
v6: take more Ville's comments:
- make was_primary bool and fix its check
- add the BDW vblank wait comment
