Commit f7b4b54e63 ("[media] tvp5150: add HW input connectors support")
added input signals support for the tvp5150, but the approach was found
to be incorrect so the corresponding DT binding commit 82c2ffeb21
("[media] tvp5150: document input connectors DT bindings") was reverted.
This left the driver with an undocumented (and wrong) DT parsing logic,
so lets get rid of this code as well until the input connectors support
is implemented properly.
It's a partial revert due other patches added on top of mentioned commit
not allowing the commit to be reverted cleanly anymore. But all the code
related to the DT parsing logic and input entities creation are removed.

MEDIA_ENT_F_CONN_TEST is not really a connector, it is actually
a signal generator. Also, as other drivers use the
V4L2_CID_TEST_PATTERN control for signal generators, let's change
the driver accordingly.
Tested with Terratec Grabster AV350.

The tvp5150 decoder has different input connectors. The actual list of
HW inputs depends on the device version but all have at least these 3:
1) Composite0
2) Composite1
3) S-Video
and some variants have a 4th possible input connector:
4) Signal generator
The driver currently uses the .s_routing callback to switch the input
connector but since these are separate HW blocks, it's better to use
media entities to represent the input connectors and their source pads
linked with the decoder's sink pad.
This allows user-space to use the MEDIA_IOC_SETUP_LINK ioctl to choose
the input connector. For example using the media-ctl user-space tool:
$ media-ctl -r -l '"Composite0":0->"tvp5150 1-005c":0[1]'

Add a header file for the tvp5150 input connectors constants that
can be shared between the driver and Device Tree source files.
