Using dev as name for variables pointing to struct ov2680_device is a bit
unfortunate choice.
All the recently added / rewritten code is already using sensor for this,
replace the remaining usages of "struct ov2680_device *dev" with
"struct ov2680_device *sensor".
Note the power_up()/power_down() related functions are not changed as
these will be removed in one of the next patches.
No functional changes.
