[PATCH v5 07/14] media: ov772x: omit consumer ID when getting clock reference

[Akinobu Mita <akinobu.mita@gmail.com>]

Currently the ov772x driver obtains a clock with a specific consumer ID.
As there's a single clock for this driver, we could omit clock-names
property in device tree by passing NULL as a consumer ID to clk_get().
