i.MX7ULP A7 core runs under control of M4 core, M4 core starts by ROM
and powers most serivces used by A7 core, so A7 core has no power to
start and stop M4 core. And the M4 core's state is default RPROC_DETACHED
and remoteproc framework not able to stop the M4 core.

They are handled by remoteproc common code, no need to map in imx
