media: i2c: ov4689: Make horizontal blanking configurable

Browse source

Make horizontal blanking configurable. To do so, set HTS register
according to the requested horizontal blanking in ov4689_set_ctrl
instead of the register table. Default HTS value is not changed by
this patch. Minimal HTS value is found experimentally and corresponds
to 90 fps framerate at minimum vertical blanking. Real HTS value is
the register value multiplied by 4.
