remoteproc: Make client initialize ops in rproc_subdev

Browse Source 
In preparation of adding the additional prepare and unprepare operations
make the client responsible for filling out the function pointers of the
rproc_subdev. This makes the arguments to rproc_add_subdev() more
manageable, in particular when some of the functions are left out.
