drm/i915: Parsing the PWM cntrl and CABC ON/OFF fields in VBT 



For dual link panel scenarios there are new fields added in the
VBT which indicate on which port the PWM cntrl and CABC ON/OFF
commands needs to be sent.

v2: Moving the comment to intel_dsi.h(Jani)

v3: Renaming the field names (Jani)

v4 by Jani: make this patch only about VBT
