  ov2680_vflip_disable() / ov2680_hflip_disable() pass BIT(0) instead of
0 as value to ov2680_mod_reg().

While fixing this also:

1. Stop having separate enable/disable functions for hflip / vflip
2. Move the is_streaming check, which is unique to hflip / vflip
   into the ov2680_set_?flip() functions.

for a nice code cleanup.

Fixes: 3ee47cad3e69 ("media: ov2680: Add Omnivision OV2680 sensor driver")
