omap: remoteproc: invoke secure services for real
The stubbed secure service authentication in the remoteproc has
been replaced with an actual rproc_drm_invoke_service function
call. This function integrates the rproc with the smc driver
allowing the actual secure services calls to authenticate and
firewall the ducati image while enabling secure mode, and
uninstall firewalls while disabling secure mode.
