remoteproc: Add remote processor coredump support
As the remoteproc framework restarts the remote processor after a fatal event, it's useful to be able to acquire a coredump of the remote processor's state, for post mortem debugging. This patch introduces a mechanism for extracting the memory contents after the remote has stopped and before the restart sequence has begun in the recovery path. The remoteproc framework builds the core dump in memory and use devcoredump to expose this to user space.
