[Intel-gfx] [PATCH v3 0/7] Add DSC PPS readout

[Suraj Kandpal]

Up until now we only verified one or two of the dsc pps
params like bits_per_component and bits_per_pixel this
patch series aim to readout almost all PPS param and get
them compared.
Along with that some work on making a common function to
read and write PPS param regiters is also done.

--v2
-Remove duplicated code and create function that fetches register
and reuse that. [Jani]
-move WARN_ON one abstraction layer up. [Jani]
-Split patch so that refactor and a new functionality is not added
in the same patch. [Jani]
-Add a new refactor patch so that bit shifting can be done in a
clean way. [Jani]

--v3
-Fix the typo in patch 2 [Jani]
-Get both dsc_reg regardless of dsc_eng_no. [Jani]
-Remove usage of num_vdsc_instances. [Ankit]
-Add macro to further optimize intel_dsc_get_pps_reg
