The cobalt driver fails to link when it is built-in and MTD is disabled or a
loadable module:
drivers/media/built-in.o: In function `cobalt_flash_probe':
:(.text+0xb8b46): undefined reference to `mtd_device_parse_register'
:(.text+0xb8b88): undefined reference to `do_map_probe'
drivers/media/built-in.o: In function `cobalt_flash_remove':
:(.text+0xb8bb4): undefined reference to `mtd_device_unregister'
:(.text+0xb8bbe): undefined reference to `map_destroy'
This adds a Kconfig dependency to ensure we can call the API.

The cobalt driver should depend on VIDEO_V4L2_SUBDEV_API.
This fixes this kbuild error:

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency of VIDEO_ADV7604 and VIDEO_COBALT (the latter
selects the former) on GPIOLIB if COMPILE_TEST is enabled.

The adv7604 driver depends on GPIOLIB, and therefore cobalt depends
on it as well.

The cobalt device is a PCIe card with 4 HDMI inputs (adv7604) and a
connector that can be used to hook up an adv7511 transmitter or an
adv7842 receiver daughterboard.
This device is used within Cisco but is sadly not available outside
of Cisco. Nevertheless it is a very interesting driver that can serve
as an example of how to support HDMI hardware and how to use the popular
adv devices.
