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.
