Linus Torvalds fdcec00405 remoteproc updates for v5.3
This adds support for the STM32 remoteproc, additional i.MX platforms
 with Cortex M4 remoteprocs and Qualcomm's QCS404 Compute DSP. Initial
 support for vendor specific resource table entries and support for
 unprocessed Qualcomm firmware files.
