Configure CSI-2 phy based on platform data in the ISP driver. For that, the
new V4L2_CID_IMAGE_SOURCE_PIXEL_RATE control is used. Previously the same
was configured from the board code.

This patch is dependent on "omap3: Provide means for changing CSI2 PHY
configuration".

Hi Sakari,

Thanks for the patch.

Not anymore. It depends on the previous patch (used to be for linux-omap
instead) so I'll remove that statement.
