remtoteproc: maintain max notifyid

Browse source 
Some of the rproc drivers (STE modem specifically) needs to know
the range of the notification IDs used for notifying the device.

Maintain a variable in struct rproc holding the largest allocated
notification id, so low-level rproc drivers could access it.
