Subject: [PATCH v4 13/25] media: i2c: imx258: Correct max FRM_LENGTH_LINES value

From: Dave Stevenson <dave.stevenson@...pberrypi.com>

The data sheet states that the maximum value for registers
0x0340/0x0341 FRM_LENGTH_LINES is 65525(decimal), not the
0xFFFF defined in this driver. Correct this limit.
