This reverts commit 0b02c8589d.
Originally change was reverted as it was making ap_compute test on
embedded-qnx-hv e3550-t194 fail. With fixes related to replacing tsg
preempt with runlist preempt during teardown, preempt timeout set to
100 ms (earlier this was set to 1000ms for t194 and 3000ms for legacy
chips) and not issuing preempt timeout recovery if preempt fails, helped
resolve the issue.

-During polling eng preempt done, reset eng only if eng stall
intr is pending. Also stop polling for eng preempt done
if eng intr is pending.
-Add max retries for pre-si platforms for poll pbdma and eng
preempt done polling loops.

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.

Reorganize HAL initialization to remove inheritance and construct
the gpu_ops struct at compile time. This patch only covers the mc
sub-module of the gpu_ops struct.
Perform HAL function assignments in hal_gxxxx.c through the
population of a chip-specific copy of gpu_ops.
