drm/amd/display: Add DMU crash recovery callback to DM

[Why]
To improve reliability of the system in the case of infrequent or
potentially recoverable hangs when the DMU times out.

[How]
Attempt to recover the ASIC when DMU hangs by triggering a crash
recovery callback for the DM to forward to the base driver.
