Now, just two routines are enough for analog: the first one configs the analog
part and register V4L2 devices, and the second one release analog devices.
After this patch, it will be easier to transform em28xx-video into an em28xx
extension, loaded only on analog devices.

em28xx-video were holding several code that are not specific to V4L2
interface.
This patch moves the core code for em28xx-core, and usb probing code
into em28xx-cards.
This opens the possibility of breaking em28xx into a core module and a
V4L2 module, loaded only on devices that have analog interfaces.
Some cleanup may be done at em28xx-cards to optimize the config code.

dib7000p.h defines a few extern symbols when CONFIG_DVB_DIB7000P is not set. since the
header is used on more than one driver, this causes symbol duplication, as pointed by

Drivers that use v4l2_device can set that as parent pointer in the v4l2_dev
field instead of using the struct device parent field.
This allows v4l2-dev.c to check whether this driver is v4l2_device based,
and if so then it can offer additional services.

Instead of relying on the cdev release callback we should rely on the
release callback from the device struct. This requires that we use
get_device/put_device to do proper refcounting. In order to do this
safely v4l2-dev.c now sets up its own file_operations that call
out to the driver's ops.

Converted to v4l2_subdev. While doing that I also discovered a stray 'break'
that broke the S_CTRL handling. Fixed that as well.
