[media] coda: export auxiliary buffers via debugfs
This patch exports all auxiliary buffers, including SRAM, as debugfs binary blobs for debugging purposes. It shows, for example, that psbuf currently doesn't seem to be used at all on CODA7541, and that slicebuf and workbuf usage is far from the maximum. It can also be used to validate SRAM size allocation.
