Nicholas Kazlauskas 8c7aea404d drm/amd/display: Perform DMUB hw_init on resume
[Why]
The DMUB is put into reset on suspend and is not running on resume,
disabling PSR/ABM features.

[How]
Move the allocation of the framebuffer to sw_init.

Do DMUB hardware init and framebuffer filling only from hw_init.

On resume the contents of the framebuffer will be invalid so those
should be cleared.
