[why]
PSR-SU is implemented in upstreamed dmub FW but not enabled on
DM and DC. We'd add necessary and missing definitions in dmub
cmd header to align w/ the up-to-date DMUB FW for PSR-SU support.

[how]
Add definitions and items below into dmub cmd header:
- DMUB psr version enumeration for PSR-SU
- dirty rectangle structure
- psr debug flag of forcing full frame update
- dmub command of updating dirty rectangle and cursor infor
- dmub psr command type of setting sink vtotal in PSR active
- dmub psr su debug flags structure
- dmub cmd structure for
  - updating dirty rectangle
  - cursor infor
  - setting sink vtotal
- dmub ringbuffer command items
