Resource table is used by Linux to get information pubished by
remote processor. It should be not be used for memory allocation, so
not create rproc mem entry.

Any reason the handling of vdev0buffer is using strcmp() and the resource table
strncmp()?

I thought rsc-table0/1 maybe there for cm40/cm41, but rsc-table should also be
ok, will use strcmp in v4.
