remoteproc updates for v6.9 

Qualcomm SM8650 audio, compute and modem remoteproc are added. Qualcomm
 X1 Elite audio and compute remoteprocs are added, after support for
 shutting down the bootloader-loaded firmware loaded into the audio DSP..
 
 A dozen drivers in the subsystem are transitioned to use devres helpers
 for remoteproc and memory allocations.
 
 It makes it possible to acquire in-kernel handle to individual
 remoteproc instances in a cluster.
 
 The release of DMA memory for remoteproc virtio is corrected to ensure
 that restarting due to a watchdog bite doesn't attempt to allocate the
 memory again without first freeing it.
 
 Last, but not least, a couple of DeviceTree binding cleanups.
