commit ba10f8d92a2c026b1052b4c0fa2cd7538838c965 upstream.
[Why]
Newer VPE microcode has functionality that will decrease DPM level
only when a workload has run for 2 or more seconds. If VPE is turned
off before this DPM decrease and the PMFW doesn't reset it when
power gating VPE, the SOC can get stuck with a higher DPM level.
This can happen from amdgpu's ring buffer test because it's a short
quick workload for VPE and VPE is turned off after 1s.
[How]
In idle handler besides checking fences are drained check PMFW version
to determine if it will reset DPM when power gating VPE. If PMFW will
not do this, then check VPE DPM level. If it is not DPM0 reschedule
delayed work again until it is.

Some version of BIOS does not enable all clock levels,
resulting in high level clock frequency of 0.
The number of valid CLKs must be confirmed in advance.

The vpe dpm settings should be done before firmware is loaded.
Otherwise, the frequency cannot be successfully raised.
