Now that we have a function that reads any PPS register based
on intel_dsc_pps enum provided lets create a function that can
write on any PPS.
--v2
-Changes need as PPS enum was dropped
-Remove duplicated code in intel_dsc_write_pps_reg [Jani]
--v3
-Use dsc_split instead of num_vdsc_instances [Ankit]
