In the rproc_attach() function, if rproc_handle_resources() returns
failure, if the rproc->ops->unprepare callback function is not set,
the resources allocated by rproc_prepare_device() cannot be released,
and rproc->clean_table should also be released

patch1 adds rproc->ops->unprepare callback function to imx_rproc
patch2 releases rproc->clean_table
