drm/amd/display: Add PSR SMU Interrupt support
[WHY]
We have new bios capabilities enabling s0i2 entry on SMU interrupt. We want
this interrupt to be fired on PSR transitions such that we enter s0i2
when entering PSR active.
[HOW]
Add code to send the SMU interrupt with the appropriate
staticscreen flag when entering and exting PSR. Protect this
code with a config flag since it currently impacts BL PWM.
