media: i2c: imx219: Scale the pixel rate for analog binning

Browse source

When the analog binning mode is used for high framerate operation, the
pixel rate is effectively doubled. Account for this when setting up the
pixel clock rate, and applying the vblank and exposure controls.

The previous logic only used analog binning for RAW8, but normal binning
limits the framerate on RAW10 480p [1]. So with this patch we switch to
using special binning (with 2x pixel rate) wherever possible.
