remoteproc: Add prepare and unprepare ops
On some SoC architecture, it is needed to enable HW like
clock, bus, regulator, memory region... before loading
co-processor firmware.
This patch introduces prepare and unprepare ops to execute
platform specific function before firmware loading and after
stop execution.
