[PATCH v2] remoteproc: virtio: Fix warning on bindings by removing the of_match_table

[PATCH v2] remoteproc: virtio: Fix warning on bindings by removing the of_match_table

[Arnaud Pouliquen]

The checkpatch tool complains that "virtio,rproc" is not documented.
But it is not possible to probe the device "rproc-virtio" by declaring
it in the device tree. So documenting it in the bindings does not make
sense.
This commit solves the checkpatch warning by suppressing the useless
of_match_table.

Updates vs previous revision:
- replace the "of_platform.h" include by "platform_device.h",
- replace "Fix-suggested-by" by "Suggested-by",
- add Rob's Reviewed-by.

Perhaps reworded a bit as:

   "Since it is not possible to probe the device "rproc-virtio" by
   declaring it in the device tree, documenting it in the bindings
   does not make sense."
