rpmsg client drivers are allowed to invoke rproc_report_crash() on their
grandparent when they determine that the otherwise seemingly healthy
remoteproc has entered a functionally broken state.
In the crash handling path qcom_q6v5_request_stop() is invoked, which is
based on the current rproc state whether to request a graceful shutdown.
But the current rproc `state` will be RPROC_CRASHED regardless of where
the crash handler was initiated from, and empirical data shows that
unless the firmware is taking part of the shutdown the system state is
often left such that it's not possible to start the subsystem again.
Use the `running` state in the q6v5 driver to make the decision instead,
as this does represent the actual state of the firmware.
This makes it possible to reliably trigger a restart from client
drivers.
