Check for interrupts or hangs while waiting for the preempt to complete.
During pbdma/eng preempt done polling, any stalling interrupts relating
to the runlist must be detected and handled in order for the preemption
to complete.
When PBDMA fault or CE fault occurs, the PBDMA will save out
automatically. TSG related to the context in which the fault occurred
will not be scheduled again until the fault is handled.
In the case of some other issue requiring the engine to be reset, TSG
will need to be manually preempted.
In all cases, a PBDMA interrupt may occur prior to the PBDMA being able to
switch out. SW must handle these interrupts according to the relevant handling
procedure before the PBDMA preempt can complete.
Opt for eng reset instead of waiting for preemption to be finished when
there is any stall interrupt pending during engine context preempt completion.

-Program mc_elpg_enable and mss nvlink soc credits only

hot reset sequence. As part of gpu unpowergate, bpmp will
program mc_elpg_enable and also set mss nvlink soc credits

-Remove updating mc_enable as writes to this register has no

Also remove the fuse override functionality from dGPU. There are no
