From: Shravan Chippa <shravan.chippa@microchip.com>

For evry mode we will get new set of values for hbalnk so use
__v4l2_ctrl_modify_range() to support multi modes for hblank.

The hblank value is readonly in the driver. because of this the function
returns error if we try to change. so added dumy return case in
imx334_set_ctrl function.
