Changed paths: M lib/include/openamp/virtio.h
Log Message: ----------- virtio.h: add memory operation for virtio device
Buffer management is different for different transport layer:
For MMIO transport layer, the buffer can direclty malloced from the gust os heap beacase the hypervisor can access all the memmory own by guest os.
For remoteproc transpor layer, the buffer should be malloced from the share memory region to make sure the remote core can access this buffer too.
So add memory ops in virtio device to make different transport/device can implement their own share memory management.
