remoteproc: export rproc_error_reporter function
The rproc_error_reporter function is currently being used to
report MMU faults and trigger a recovery. This is internal to
the remoteproc framework.
However, the function can be used to report errors other than
just iommu faults, like errors that a remoteproc detects and
notifies the remoteproc driver. The rproc_error_reporter
function therefore is now exported to allow other clients to
report an error.
