Media Kconfig menu reorg and improvements

The media Kconfig menu is complex. From time to time, it requires some improvements.

This series is organized on two parts:

1. Patches 1 to 19: cleanups and improvements;

- Try to be smarter when selecting features. So, auto-select Cypress firmware support on drivers that use it. Also, auto-select Media Controller and V4L2 subdevice API for devices that won't work without such features.

Please notice that some drivers have can work optionally with those features enabled (or not). For those, users should still explicitly enable such features.

- Platform and test drivers have now an option at the device support selection;

- The test drivers are not platform drivers. They deserve their own directory. When a test driver is selected, the needed API support will be automatically selected.

- Do some Kconfig reorg, in order to keep the main media Kconfig as clean as possible.

- The help messafe for media support was outdated;

- The ddbridge driver was abusing at the dvb dummy frontend driver (meant to be just an example). It will now have its own internal dummy driver, as the original one will soon receive more code and become a virtual driver.

- There's a longstanding issue with hybrid TV devices: for an hybrid device to work, *both* analog and digital TV would need to be selected. As the Kconfig language improved, we can now address it. So, selecting either analog or digital TV support should display all hybrid devices. When an hybrid driver is selected, both V4L2 and DVB core will be available.

2. Patches 20 to 33: visual changes.

- At the beginning, media had just "technical" options to enable/disable each feature. However, that leads into hundreds of different options, being a nightmare for a mortal to set it up.

So, the Kconfig menu options were re-designed in order to bring a more user-oriented view:

The initial items select the type of devices (analog TV, digital TV, cameras, ...). Selecting it would auto-select the core drivers. The next step would be to select either PCI or USB, and the needed driver.

While this makes life simpler, now there are many embedded developers. Most seem to prefer to be able of seeing everything without filters.

The main focus of this part is to make everybody
happy: it is now possible to unselect the filters, making all options visible. Also, now, when the filter is enabled, the media drivers menu will show a message warning that the filter is active.

Hopefully, this should make both embedded developers and normal users happy.

- The media menus now have a more modern visual, grouping options in a way that it is now clearer about what they do.

So, the Media support menu is now:

	--- Media support
	[ ] Filter media drivers
	[ ] Autoselect ancillary drivers
	    Media device types --->
	    Media core support --->
	    Video4Linux options --->
	    Media controller options --->
	    Digital TV options --->
	    HDMI CEC options --->
	    Media drivers --->
	    Media ancillary drivers --->
