drm/amdkfd: implement per queue sdma reset for gfx 9.4+

To reset hung SDMA queues on GFX 9.4+ for the GFX9 family, a soft reset
must be issued through SMU.  Since soft resets will reset an entire SDMA
engine, use a common KGD call to do the reset as the KGD will handle
avoiding a reset of in flight GFX and paging queues on that engine.

In addition, create a common call for all reset types to simplify
the handling of module parameter settings that block gpu resets.
