media: cx231xx: convert to the vb2 framework

This patch converts the cx231xx driver to the vb2 framework.
Since you can't do a partial conversion this is a big-bang patch,
i.e. large and hard to review. I never found a way around this.

[media] cx231xx: fix GPIOs for Pixelview SBTVD hybrid

This device uses GPIOs: 28 to switch between analog and

The code that sets it on analog mode is OK, but it misses

Except for the usbuvc driver (with has an embedded media_device

one. That warrants that those subdev drivers will fill the

[media] media-device: split media initialization and registration

The media device node is registered and so made visible to user-space
before entities are registered and links created which means that the
media graph obtained by user-space could be only partially enumerated
if that happens too early before all the graph has been created.

To avoid this race condition, split the media init and registration
in separate functions and only register the media device node when
all the pending subdevices have been registered, either explicitly
by the driver or asynchronously using v4l2_async_register_subdev().

The media_device_register() had a check for drivers not filling dev
and model fields but all drivers in mainline set them and not doing
it will be a driver bug so change the function return to void and
add a BUG_ON() for dev being NULL instead.

Also, add a media_device_cleanup() function that will destroy the
graph_mutex that is initialized in media_device_init().

[media] media-entity.h: rename entity.type to entity.function

Entities should have one or more functions. Calling it as a
type proofed to not be correct, as an entity could eventually
have more than one type.

So, rename the field as function.

Please notice that this patch doesn't extend support for
multiple function entities. Such change will happen when
we have real case drivers using it.

No functional changes.

[media] media: rename the function that create pad links

With the new API, a link can be either between two PADs or between an interface

So, rename the such function to media_create_pad_link().

And the references for those headers were corrected using:

[media] cx231xx: fix compiler warning

Fix this compiler warning by allocating a structure to read the eeprom instead
of doing it on the stack and worse: the eeprom array is static, so that can
cause problems if there are multiple cx231xx instances.

cx231xx-cards.c:1110:1: warning: the frame size of 2064 bytes is larger than 2048 bytes [-Wframe-larger-than=]
}
^

I did consider removing the code altogether since the result is actually
not used at the moment, but I decided against it since it is used in other
drivers and someone might want to start using it in this driver as well. And
then it is useful that the code is already there.

moves usb_get_dev(interface_to_usbdev(interface)) to the beginning
of cx231xx_usb_probe() to use udev->dev in dev_err(),
but it does not make sure usbdev is put on all failure paths.

Later dev_err(udev->dev) was replaced by dev_err(d).

Unfortunately, on devices that have multiple interfaces, udev->dev

as if they were produced by USB core:
usb-1-2: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces

Instead of using the name of the parent device, let's use the name
of the first cx231xx interface for all cx231xx sub-modules.

With this path, the logs will be nicer:

- long strings broken into multiple lines;
- some printks just produce ugly reports, being almost useless
as-is.

Do a cleanup on that.

Still, there are much to be done in order to do a better printk
job on this driver, but, at least it will now be a way less
verbose, if debug printks are disabled, and some logs might
actually be useful.
