Currently there is no easy way to enable mem2mem based video
processor drivers (cedrus for example). Simplify this by adding
separate category to media support.

Hmm... this patch looks incomplete. I mean, the main goal of those
MEDIA_*_SUPPORT is to make simpler for the users to select a
subset of the drivers. Those options actually make visible
the corresponding entries for pci/usb/... drivers. So,
for example, drivers/media/usb/Kconfig contains:

	if MEDIA_CAMERA_SUPPORT
		comment "Webcam devices"
	source "drivers/media/usb/uvc/Kconfig"
	source "drivers/media/usb/gspca/Kconfig"
	source "drivers/media/usb/pwc/Kconfig"
	source "drivers/media/usb/cpia2/Kconfig"
	source "drivers/media/usb/zr364xx/Kconfig"
	source "drivers/media/usb/stkwebcam/Kconfig"
	source "drivers/media/usb/s2255/Kconfig"
	source "drivers/media/usb/usbtv/Kconfig"
	endif

If we'll be adding it, I would expect a corresponding change at
drivers/media/platform/Kconfig.

Thanks,
Mauro

Thanks, I will look into it. The current approach at least made it
somewhat easier to enable sunxi-cedrus via menuconfig.
