From: Stanimir Varbanov <svarbanov@xxxxxxxxxx>
The omap3isp platform device requires platform data. As the data can be
provided by a kernel module, the device can't be registered during arch
initialization.
Remove the omap3isp platform device registration from
omap_init_camera(), and export the platform device structure to let
board code register/unregister it.
