This commit enables the SubVP feature. To achieve that, we need to:

- Don't force p-state disallow on SubVP (can't block dummy p-state)
- Send calculated watermark to DMCUB for SubVP
- Adjust CAB mode message to PMFW
- Add a proper locking sequence for SubVP
- Various fixes to SubVP static analysis and determining SubVP config
- Currently SubVP not supported with pipe split so merge all pipes
  before setting up SubVp

[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

[Why?]
On wake from S3/S4, driver checks if DMUB is initialized. On S4 VBIOS loads
DMUB, and driver does not reload as it appears to be initialized already.

[How?]
Add a check for the DAL_FW bit to ensure that loaded FW is from driver and
not VBIOS.

Disable DMUB Outbox0 interrupt

[WHY]
Very low rate to cause memory access issue while resetting
DMCUB after the halt command was sent to it.
The process of stopping fw of DMCUB may be timeout, that means
it is not in idle state, such as the window frames may still be
kept in cache, so reset by force will cause MMHUB hang.

[HOW]
After the halt command was sent, keep checking the DMCUB state until
it is idle.

Fix the kernel test robot warning below:

drivers/gpu/drm/amd/amdgpu/../display/dmub/inc/dmub_cmd.h:2893:12:
warning: variable 'temp' set but not used [-Wunused-but-set-variable]

Replaced the assignment to the unused temp variable with READ_ONCE()
macro to flush the writes. READ_ONCE() helps avoid the use of
volatile and makes it obvious from the code that the read here is
intentional. Also verified on x86 that the generated code is exactly the
same as before.
