[media] vivi: Constify structures
Most of *_ops and other structures in vivi.c were already declared const
but some have not. Constify and code/data will take less space:
$ size drivers/media/platform/vivi.o
text data bss dec hex filename
before: 12569 248 8 12825 3219 drivers/media/platform/vivi.o
after: 12308 20 8 12336 3030 drivers/media/platform/vivi.o
i.e. vivi.o is now ~500 bytes less.
