remoteproc: Allow shutdown of crashed processors

Browse source

rproc_shutdown() rejects a remoteproc in RPROC_CRASHED state, and
rproc_del() ignores that error. The result of these two decisions is
that a user cannot stop a remoteproc that with recovery disabled that
has entered a crash state, and removal of an associated remoteproc
driver will release resources without first stopping the remoteproc.

Allow rproc_shutdown() to stop crashed processors. Propagate the crash
state to subdevice teardown, to allow subdevices to dismantle things
appropriately.
