[PATCH v2] media: i2c: ov5645: Correct Y_OFFSET value at 2592x1944 resolution

[Changwei Zou]

The Y_OFFSET register at (0x3812, 0x3813) is set to 6, which is
inconsistent with the OV5645 datasheet and the X_OFFSET setting.
For consistency and clarity, change the value from 6 to 4.

height = (Y_ADDR_END - Y_OFFSET * 2 - Y_ADDR_START) + 1
   = (V(0x3806, 0x3807) - V(0x3812, 0x3813) * 2 - V(0x3802, 0x3803)) + 1
   = (0x079F - 4 * 2 - 0) + 1
   = (1951 - 8 - 0) + 1
   = 1943 + 1
   = 1944
