drm/amd/display: Isolate DSC module from driver dependencies
[Why] Edid Utility wishes to include DSC module from driver instead of doing it's own logic which will need to be updated every time someone modifies the driver logic. [How] Modify some functions such that we dont need to pass the entire DC structure as parameter. -Remove DC inclusion from module. -Filter out problematic types and inclusions Signed-off-by: Bayan Zabihiyan <bayan.zabihiyan@amd.com> Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
