Nicholas Kazlauskas e5f0b5214b drm/amd/display: Check hw_init state when determining if DMCUB is initialized
[Why]
CW2 may already be programmed when coming back from S4. In this case
we want to unconditionally replace whatever DMCUB version is currently
enabled with the latest.

[How]
Check the hw_init flag to know whether or not we've previously executed
the initliazed routine.
