0693bdf754 [media] dvb: Remove unused frontend sources at demux.h and sync doc
The DVB core has a provision for other frontend sources, but no
drivers use it. The kdapi.xml contains provision for some other
frontend source types, but it is not in sync with the code.

So, remove the unused types and sync both files.

2f684b239c [media] dvb: get rid of enum dmx_success
This enum is not actually used anymore. The only value used from
the enum is DMX_OK, passed as a parameter on two callbacks.

Yet, this value is not used anywhere. So, just remove it.

95abfdb942 [media] DocBook: Move struct dmx_demux kABI doc to demux.h
The DocBook/media/dvb/kdapi.xml contains the description of
the kABI for DVB. The problem is that, by being maintained
on a separate file and not being updated for years, it got
outdated. So, for example, some callback parameters were
changed, but the DocBook were still using the old stuff.

As a first step to fix it, let's move the documentation of
struct dmx_demux into demux.h and fix the parameters used
there.

For now, don't document any other field nor touch the
descriptions that got moved, letting this job to other
patches. That makes easier to review the patch.

PS.: Please notice that an additional patch will be needed
in order to fix the return values (some uses non-existent
return codes) and to the functions and callbacks mentioned at
the descriptions.

60f4570de8 [media] DocBook/media: clarify control documentation
- Add missing V4L2_CTRL_TYPE_U32 documentation
- Remove 'which are actually different on the hardware' sentence which
  is confusing. I think the idea was to let the user know that the step can
  be different for different hardware, but that's obvious because otherwise
  you wouldn't need to specify the step value.
- Clarify that V4L2_CTRL_COMPOUND_TYPES also applies to arrays.
