virtio_console: Constify some static variables 

The id_table and feature_table pointers in struct virtio_driver are
pointers to const. Mark the corresponding static variables const to
allow the compiler to put them in read-only memory.

Before:
   text    data     bss     dec     hex filename
  25447     713      76   26236    667c drivers/char/virtio_console.o

After:
   text    data     bss     dec     hex filename
  25488     673      76   26237    667d drivers/char/virtio_console.o
