Add support to the K3 DSP remoteproc driver to configure all the C66x and C71x cores on J721E SoCs to be either in IPC-only mode or the traditional remoteproc mode. The IPC-only mode expects that the remote processors are already booted by the bootloader, and only perform the minimum steps required to initialize and deinitialize the virtio IPC transports. The remoteproc mode allows the kernel remoteproc driver to do the regular load and boot and other device management operations for a DSP. The IPC-only mode for a DSP is detected and configured at driver probe time by querying the System Firmware for the DSP power and reset state and/or status and making sure that the DSP is indeed started by the bootloaders, otherwise the device is configured for remoteproc mode. Support for IPC-only mode is achieved through .attach(), .detach() and .get_loaded_rsc_table() callback ops and zeroing out the regular rproc ops .prepare(), .unprepare(), .start() and .stop(). The resource table follows a design-by-contract approach and is expected to be at the base of the DDR firmware region reserved for each remoteproc, it is mostly expected to contain only the virtio device and trace resource entries. NOTE: The driver cannot configure a DSP core for remoteproc mode by any means without rebooting the kernel if that DSP core has been started by a bootloader. This is the current desired behavior and can be enhanced in the future if the feature is needed.
