Nicholas Kazlauskas 2364076772 drm/amd/display: Add DMUB firmware state debugfs
[Why]
Firmware state helps to debug sequence issues and hangs for DMCUB
commands and we don't have an easy mechanism to dump it from the driver.

[How]
Add a debugfs entry to dump the current firmware state.
Example usage:

cat /sys/kernel/debug/dri/0/amdgpu_dm_dmub_fw_state
