dev: gcdb: Update target API in GCDB

All display specific target GPIOs, regulators and
display physical settings are part of display header
file present in target module. Target module should
access it directly from display header instead of
receiving from GCDB API. It removes unnecessary
function arguments from GCDB API and all future
target specific change won't update the GCDB code.

Support mode gpio state processing in panel display
module.
