drivers/media/video/omap3isp/isp.h is not a proper location for a header
that needs to be included from board code. Move the platform data
definitions to media/omap3isp.h.

Board code still needs to include isp.h to get the struct isp_device
definition and access OMAP3 ISP platform callbacks. Those callbacks will
be replaced by more generic code.

Thanks for the patch! I very much agree with the approach.

I applied this to my rx51 tree (yeah, nasty out-of-tree stuff, for now), and
get a bunch of errors, mostly because of missing definitions. Have you
tested the patch somewhere? :-)

At least these should be present, I think:

- v4l2_dev_to_isp_device
- isp_platform_callback
- ISP_XCLK_*
