From: Gustavo Padovan gustavo.padovan@collabora.co.uk
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)
