Subject: [PATCH v3 1/4] dt-bindings: remoteproc: mpss: Document QDU1000/QRU1000 mpss devices

From: Melody Olvera <quic_molvera@...cinc.com>

Document the compatible for the component used to boot the MPSS on the
QDU1000 and QRU1000 SoCs.

The QDU1000 and QRU1000 mpss boot process now requires the specification
of an RMB register space to complete the handshake needed to start or
attach the mpss.
