[PATCH] virtio: virtio_mmio: make of_device_ids const.

[Arvind Yadav]

of_device_ids are not supposed to change at runtime. All functions
working with of_device_ids provided by <linux/of.h> work with const
of_device_ids. So mark the non-const structs as const.

File size before:
   text    data     bss     dec     hex filename
   3647     608       0    4255    109f drivers/virtio/virtio_mmio.o

File size after constify virtio_mmio_match.
   text    data     bss     dec     hex filename
   4063     192       0    4255    109f drivers/virtio/virtio_mmio.o
