remoteproc: Add a sysfs interface for name
This patch adds a sysfs interface that provides the name of the remote processor to userspace. This allows the userspace to identify a remote processor as the remoteproc devices themselves are created based on probe order and can change from one boot to another or at runtime. The name is made available in debugfs originally, and is being retained for now. This can be cleaned up after couple of releases once users get familiar with the new interface.
