[PATCH AUTOSEL 5.10 32/41] drm/amd/display: Use hardware sequencer functions for PG control

[Sasha Levin]

From: Nicholas Kazlauskas <nicholas.kazlauskas at amd.com>

[ Upstream commit c74f865f14318217350aa33363577cb95b06eb82 ]

[Why & How]
These can differ per ASIC or not be present. Don't call the dcn20 ones
directly but rather the ones defined by the ASIC init table.
