Subject: [PATCH v3 5/6] media: imx335: Fix active area height discrepency

The imx335 reports a recommended pixel area of - 2592x1944.
The driver supported mode however limits it to height=1940.

Fix the height discrepency by correctly the value of height
(with updates to vblank and mode registers).
