Subject: [PATCH v3 1/3] remoteproc: Expose remoteproc configuration through sysfs

Add a feature flag to expose some of the remoteproc configuration
through sysfs. This feature is helpful in systems where debugfs is
not available/mounted. Currently the recovery and coredump
configuration is exposed through sysfs rather than debugfs when
this feature is selected.
