Subject: [PATCH v5 3/6] media: i2c: imx334: hblank set function modify

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

-If we one modes hblank will not change and it is readonly
-If we have multipull modes and if we do mode switch, hblank value will
change and __v4l2_ctrl_s_ctrl() returns error, so modified
function from __v4l2_ctrl_s_ctrl() to __v4l2_ctrl_modify_range()
will updated all values max, min default it is not showing any error
while changing the mode and update value
