[PATCH 06/25] drm/amd/display: Pass sequential ONO bit to DMCUB boot options

[Rodrigo Siqueira]

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

[Why]
IPS ono sequence ordering differs based on the ASIC.

[How]
Detect the ASIC ID revision and set the boot option accordingly. Feed
it through the DCN35 DMUB functions.
