media: ov2680: Fix vflip / hflip set functions
[ Upstream commit d5d08ad330c9ccebc5e066fda815423a290f48b0 ]
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.
