drm/amd/display: Blank HUBP during pixel data blank for DCN30 v2
[Why]
Prior commit "Blank HUBP during pixel data blank for DCN30"
missed the call to set_disp_pattern_generator from
set_crtc_test_pattern, which re-exposed the issue for which
we initially blocked active-only p-state switching.
[How]
- remove dcn30_blank_pixel_data, set dcn30 back to dcn20 version
- new hwss funciton set_disp_pattern_generator
- dcn20 version just calls opp_set_disp_pattern_generator
- dcn30 version implements the HUBP blank
