Subject: [PATCH v2 14/16] media: i2c: ov5647: Use the same PLL config for
 full, 1080p, and binned modes

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

In order to simplify the driver slightly, use the same PLL
configuration, and hence pixel rate and link frequency (to be
added) for the full, 1080p, and binned modes.
