This adds two more sensor modes for Omnivision ov8856 image sensor,
including the resolution of 1632*1224 and 3264*2448, both with the
Bayer Order of BGGR.

The new modes are presumably for either 19,2 or 24 MHz frequency (but which
one?) whereas the old modes were for 19,2 MHz.

This needs to be addressed, preferrably in a separate patch. The modes
should be added in another patch.

You only need this if ov8856->n_shutdn_gpio is non-NULL.

Also do add a separate patch for supporting other mbus codes if you need
them.

The function is rather enabling reading OTP memory. Also disable streaming
when you're done. This would be ideally a separate patch.

The mclk is the external clock frequency. Both 19,2 and 24 MHz need to work
if you claim to support 24 MHz.
