[Intel-gfx] [v7 0/3] Enable setting custom DSC BPP

[Vandita Kulkarni]

This series add debugfs entry to force dsc bpp to
ceratin valid test value, for validation needs.
This series has been tested locally.
With the introduction of i915_dsc_bpp debugfs
the expectation is that whenever there is force_dsc_en
set, force_dsc_bpp should have a valid value for that
format which is between bpp to bpp-1.

This makes the older test kms_dp_dsc --basic fail
as in that case force_dsc_bpp would be 0 and is not a valid
value.

Have tested with local changes on the same.
The series https://patchwork.freedesktop.org/series/91772/
have the base patches and would need some work on the debugfs name
change, giving default value for force_dsc_bpp in case of
basic-dsc-enable
test cases, clearing up of the force_dsc_bpp value while exiting the
test. Which will be floated shortly.

Have added minor fix on the feci debugfs interface.
If further changes are needed on the same will float them in a different
series.
