qcom_q6v5 is requesting a smem state with qcom_smem_state_get() but
qcom_smem_state_put() is not called anywhere. Use the new devm_()
variant to fix this without making the code more complicated.

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.

Sometimes the stop triggers a watchdog rather than a stop-ack. Update
the running state to false on requesting stop to skip the watchdog
instead.

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.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>
@@
expression ret;
struct platform_device *E;
@@
ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);
if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>
While we're here, remove braces on if statements that only have one
statement (manually).

Commit d5269c4553a6 ("remoteproc: qcom: q6v5: Propagate EPROBE_DEFER")
fixed up our probe code to handle -EPROBE_DEFER, but it ignored one of
our interrupts, and it also didn't really handle all the other error
codes you might get (e.g., with a bad DT definition). Handle those all
explicitly.

Currently with GLINK_SSR enabled each fatal crash results in servicing
a crash from wdog as well. This is due to a race that occurs in setting
the running flag in the shutdown path. Fix this by moving the running
flag to the end of fatal interrupt handler.

In the case that the interrupts fail to result because of the
interrupt-controller not yet being registered the
platform_get_irq_byname() call will fail with -EPROBE_DEFER, but passing
this into devm_request_threaded_irq() will result in -EINVAL being
returned, the driver is therefor not reprobed later.

The new driver only works as built-in code at the moment but fails

This exports the internal symbols as needed and adds the MODULE_LICENSE()
and MODULE_DESCRIPTION() tags. I could not figure out the author, so I
did not add a MODULE_AUTHOR() tag for now.

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.
