omap: remoteproc: add a notification for loading error
When calling rproc_get for the first time, the loading of
the remoteproc image will be requested using a non-blocking
request_firmware_no_wait, and the caller can continue before
the actual loading is complete.
The loader later can return an error due to a non-existing
or wrong image and there should be a way to notify about this
to users having a rproc handle.
This functionality is added and is leveraged by rpmsg to
release some resources it had already acquired since requesting
a firmware load.
