mic: vop: Constify static structs

vop_vq_config_ops and id_table[] are never modified so make them const
to allow the compiler to put them in read-only memory.

Before:
   text    data     bss     dec     hex filename
  14889    4065     192   19146    4aca drivers/misc/mic/vop/vop_main.o

After:
   text    data     bss     dec     hex filename
