firmware: arm_scmi: Protect device request lookup with RCU
The SCMI device request notifier looks up protocol OF nodes from the
active_protocols IDR. The IDR lookup can run concurrently with protocol
activation while probe is still registering protocols and creating their
SCMI devices.
Wrap the lookup in an RCU read-side critical section as required by the
IDR API for lockless readers.
