drm/amd/display: Fully switch to dmub for all dcn21 asics
[Why]
On renoir usb-c port stops functioning on resume after f/w update.
New dmub firmware caused regression due to conflict with dmcu.
With new dmub f/w dmcu is superseded and should be disabled.
[How]
- Disable dmcu for all dcn21.
Check dmesg for dmub f/w version.
The old firmware (before regression):
[drm] DMUB hardware initialized: version=0x00000001
All other versions require this patch for renoir.
