From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx>
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 unecessary 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
