drm/amd/display: Ensure that DMCUB fw in use is loaded by DC and not VBIOS
[Why?]
On wake from S3/S4, driver checks if DMUB is initialized. On S4 VBIOS loads
DMUB, and driver does not reload as it appears to be initialized already.
[How?]
Add a check for the DAL_FW bit to ensure that loaded FW is from driver and
not VBIOS.
