Subject: [PATCH] remoteproc: core: Auto select rproc-virtio device id
With multiple remoteproc device, there will below error:
sysfs: cannot create duplicate filename '/bus/platform/devices/rproc-virtio.0'
The rvdev_data.index is duplicate, that cause issue, so
need to use the PLATFORM_DEVID_AUTO instead.
Fixes: 1d7b61c06dc3 ("remoteproc: virtio: Create platform device for the remoteproc_virtio")
