Subject: [PATCH v2 2/2] remoteproc: k3-c7x: Add support for C7xv DSP on AM62A SoC

From: Jai Luthra <j-luthra@...com>

Add support to the K3 DSP remoteproc driver to configure the C7xv
subsystem core on AM62A SoCs. The C7xv susbsytem is based on C71 DSP
with anlytics engine for deep learning purposes. The remoteproc
handling for device management is similar to the C66/C71 DSPs on K3
J7 family SoCs, even though there are additional hardware accelerators
and IP updates to C7xv subsystem.
