media: omap3isp: add V4L2_CAP_IO_MC and don't set bus_info

Since this is a media-centric device set the V4L2_CAP_IO_MC
capability. Also don't set bus_info, leave that to the v4l2 core.

This fixes v4l2-compliance errors:

test MC information (see 'Media Driver Info' above): OK
	fail: v4l2-compliance.cpp(661): missing bus_info prefix ('media')
