Rikard Falkeborn bb7eda7edd remoteproc: ingenic: Constify ingenic_rproc_ops 
The only usage of ingenic_rproc_ops is to pass its address to
devm_rproc_alloc(), which accepts a const pointer. Make it const to
allow the compiler to put it in read-only memory.

Mathieu Poirier 4605ad8f45 remoteproc: ingenic: Move clock handling to prepare/unprepare callbacks 
This patch moves clock related operations to the remoteproc prepare()
and unprepare() callbacks so that the PM runtime framework doesn't
have to be involved needlessly.  This provides a simpler approach and
requires less code.

Based on the work from Paul Cercueil published here:
