Bjorn Andersson	ed5da80873	remoteproc: qcom: q6v5: Query sysmon before graceful shutdown ... Requesting a graceful shutdown through the shared memory state signals will not be acked in the event that sysmon has already successfully shut down the remote firmware. So extend the stop request API to optionally take the remoteproc's sysmon instance and query if there's already been a successful shutdown attempt, before doing the signal dance.

Bjorn Andersson	e9142f5c28	remoteproc: qcom: q6v5: Add common panic handler ... Add a common panic handler that invokes a stop request and sleep enough to let the remoteproc flush it's caches etc in order to aid post mortem debugging. For now a hard coded 200ms is returned to the remoteproc core, this value is taken from the downstream kernel.

Bjorn Andersson	3b415c8fb2	remoteproc: q6v5: Extract common resource handling ... Shared between all Hexagon V5 based remoteprocs is the handling of the 5 interrupts and the SMP2P stop request, so break this out into a separate function in order to allow these drivers to be cleaned up.
