Revert "media: Kconfig: better support hybrid TV devices"

Changing from "depends on" to "select" may cause some
side-effects. This patch is not ready to be merged yet,
as it requires some adjustments.

So, let's revert it.

This reverts commit a3b91d8bd1e034c8ed89d3f55243478af97a0a52.

media: Kconfig: better support hybrid TV devices

Right now, if one has an hybrid TV card, it has to select
both analog and digital TV support, as otherwise the needed
core support won't be selected.

media: Kconfig: better support hybrid TV devices

Right now, if one has an hybrid TV card, it has to select
both analog and digital TV support, as otherwise the needed
core support won't be selected.

Change the logic to auto-select the core support for those
drivers, as this is a way more intuitive.

It should be noticed that, as now both DVB_CORE and VIDEO_DEV
defaults depends on selecting a hybrid cards, we had to remove
the explicit dependencies there, in order to avoid circular
dependencies.

That requires some tricks:

1) the prompt should not be not visible when an hybrid card
is selected, as the user shold not change it.

2) When a media hybrid device is selected, the modular
option for DVB_CORE and VIDEO_DEV will follow the
MEDIA_SUPPORT dependency, as we can't have a core
built with "y" with a driver built as module.

Note: while here, moved two pure V4L2 PCI drivers out of the
"hybrid" part of config and consider pvrusb2 as an hybrid
device.
