V4L/DVB (10072): soc-camera: Add signal inversion flags to be used by camera drivers
As reported by Antonio Ospite <ospite@studenti.unina.it> two platforms with a mt9m111 camera require opposite pixel clock polarity, which means one of them inverts it. This patch adds support for inversion flags and switches all available camera drivers to using them.
