The !crtc->enabled case will now be handled by the !visible code, since the handling is basically the same.

Factor out a piece of code from intel_pipe_set_base() that updates the pipe size and adjust fitter.
This will help refactor the update primary plane path.
v2: use struct intel_crtc as argument to intel_update_pipe_size()

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
