Revert "remoteproc: Merge table_ptr and cached_table pointers"
Following any fw_rsc_vdev entries in the resource table are two variable length arrays, the first one reference vring resources and the second one is the virtio config space. The virtio config space is used by virtio to communicate status and configuration changes and must as such be shared with the remote. The reverted commit incorrectly made any changes to the virtio config space only affect the local copy, in an attempt to allowing memory protection of the shared resource table. This reverts commit cda8529346935fc86f476999ac4fbfe4e17abf11. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
