The workaround can be applied only with UCLK DPM enabled.
And expand the workaround to more Navi10 SKUs and also
Navi14.

Drop the unused message(SMU_MSG_DAL_DISABLE_DUMMY_PSTATE_CHANGE).
And do not apply this workaround when the max uclk frequency
is greater than 750Mhz.

At this point the ASIC is already post reset by the HW/PSP
so the HW not in proper state to be configured for suspension,
some blocks might be even gated and so best is to avoid touching it.

The target is to provide a clear entry point(for power routines).
Also this can help to maintain a clear view about the frameworks
used on different ASICs. Hopefully all these can make power part
more friendly to play with.
