Eric Yang 8f95ff284c drm/amd/display: add mechanism to skip DCN init
[Why]
If optimized init is done in FW. DCN init be skipped in driver. This
need to be communicated between driver and fw and maintain backwards
compatibility.

[How]
Use DMUB scratch 0 bit 2 to indicate optimized init done in fw and
use DMUB scatch 4 bit 0 to indicate drive supports the optimized flow
so FW will perform it.
