This patch adds support for collecting minidump in the event of remoteproc crash. Parse the minidump table based on remoteproc's unique minidump-id, read all memory regions from the remoteproc's minidump table entry and expose the memory to userspace. The remoteproc platform driver can choose to collect a full/mini dump by specifying the coredump op.
