[PATCH 05/11] media: exynos4-is: Improve support for sensors with multiple pads

[Jonathan Bakker]

Commit 1c9f5bd7cb8a ("[media] s5p-fimc: Add support for sensors with
multiple pads") caught the case where a sensor with multiple pads was
connected via CSIS, but missed the case where the sensor was directly
connected to the FIMC.

This still assumes that the last pad of a sensor is the source.
