firmware: arm_scmi: Ensure drivers provide a probe function
commit 5e469dac326555d2038d199a6329458cc82a34e5 upstream.
The bus probe callback calls the driver callback without further
checking. Better be safe than sorry and refuse registration of a driver
without a probe function to prevent a NULL pointer exception.
