potential race conditions.

After a full device reset, shared memory region will clear out and it's
not possible to reliably save the region in case of RAS errors.
Reinitialize the flags if required.

For vcn_v_5_0_1, set power state to gating during hw fini. Also there may
be scenario where VCN engine hangs during a job execution, then it's not
safe to assume that set_pg_state works fine during hw_fini to put the state
to gated. After a reset, we can assume that it's in the default state,
therefore reset the driver maintained state. Put the default state as gated
during reset as per this assumption.

VCN v5.0.1 also will need register offset normalization. Reuse the logic
from VCN v4.0.3. Also, avoid HDP flush similar to VCN v4.0.3

Pass the vcn instance structure to these functions rather
than adev and the instance number.
TODO: clean up the function internals to use the vinst state
directly rather than accessing it indirectly via adev->vcn.inst[].

Have a separate work handler for each VCN instance. This
paves the way for per instance VCN power gating at runtime.

Split the code on a per instance basis. This will allow
us to use the per instance functions in the future to

However, this happened in parallel to the vcn 5.0.1
