Yes it is. You will just need to call omap3_init_camera() in your board code 
with a pointer to platform data that contain an empty list of subdevs. 
Something like

static struct isp_v4l2_subdevs_group beagle_camera_subdevs[] = {
	{ },
};

static struct isp_platform_data beagle_isp_platform_data = {
	.subdevs = beagle_camera_subdevs,
};

static int __init beagle_camera_init(void)
{
	if (!machine_is_omap3_beagle())
		return 0;

	omap3_init_camera(&beagle_isp_platform_data);

	return 0;
}
late_initcall(beagle_camera_init);

should do (you will also need to include the appropriate headers).
