remoteproc: xlnx: Refactor start & stop ops

Browse source

Current _start and _stop ops are implemented using various APIs from the
platform management firmware driver. Instead provide respective RPU
start and stop API in the firmware driver and move the logic to interact
with the PM firmware in the firmware driver. The remoteproc driver doesn't
need to know actual logic, but only the final result i.e. RPU start/stop
was success or not. This refactor keeps the remoteproc driver simple and
moves firmware interaction logic to the firmware driver.
