Subject: [PATCH v4 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).

The IMX335_REG_HTRIMMING should also be corrected to the start
offset(i.e. 48) instead of chosing a abritrary crop start of 384.
