msm: drm: uapi: Add PCC flag to specify PCC evaluation position

Browse Source 
A new position control register has been added to the DSPP PCC
on Lahaina. This register controls whether PCC is invoked
before or after GAMUT mapping.

Introduce a PCC UAPI flag to indicate if PCC should be placed
before the GAMUT block. By default PCC will be placed after
GAMUT.
