media: ov02c10: Remove unnecessary hflip and vflip pointers

The cci_update_bits() inside ov02c10_set_ctrl() can use the passed
data in the ctrl argument to access the vflip control value.

After changing this there is no need to store a pointer to the hflip
and vflip controls inside struct ov02c10, drop these.
