disp: msm: sde: Add support for PCC position field

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

Introduce new PCC control logic to set the PCC position based on
the new PCC_BEFORE flag. Older versions of the PCC control function
now clear all flags to ensure backwards compatibility.
