drivers: remoteproc: constify rproc_ops structures

Declare rproc_ops structures as const as they are only passed as an
argument to the function rproc_alloc. This argument is of type const, so
rproc_ops structures having this property can be declared const too.
Done using Coccinelle:

@r1 disable optional_qualifier @
identifier i;
position p;
@@
static struct rproc_ops i@p = {...};

@ok1@
identifier r1.i;
position p;
@@
rproc_alloc(...,&i@p,...)

@bad@
position p!={r1.p,ok1.p};
identifier r1.i;
@@

@depends on !bad disable optional_qualifier@
identifier r1.i;
