Add a generic way to create jack inputs for auxiliary jack detection
drivers (e.g. via i2c, spi), which are not part of any real codec.
The simple-card can be used as combining card driver to add the jacks,
no new one is required.

Create a jack (for input-events) for jack devices in the auxiliary
device list (aux_devs). A device which returns a valid value on
get_jack_type counts as jack device; set_jack is required
to add the jack to the device.

The of_get_next_child() returns a node with refcount incremented, and
decrements the refcount of prev. So in the error path of the while loop,
of_node_put() needs be called for cpu_ep.

Audio Graph Card2 has been announcing "Audio Graph Card2 is
still under Experimental stage", but it is time to remove it.
This patch removes it.

DPCM connection on Card2, its DT looks like below.
Current Card2 is checking (a)/(b) part only for convert-xxx settings.
But it is not useful. This patch enables its settings at (A)/(B) part
too. (A)/(B) settings will be overwritten (a)/(b) settings if it has.

<Image>		      (A)	(a)
	Card2 <--+--> FE <---> CPU

		...
		links = <fe, be>; /* (A) (B) */
	};

	dpcm {

		ports@0 {

			fe: port { fe_ep: endpoint { remote-endpoint = <&cpu_ep>; } };
		};

		ports@1 {
			/* (B) */
			be: port {
				convert-rate = <44100>; /* This patch enables this */
				be_ep: endpoint { remote-endpoint = <&codec_ep>; }
			};
		};
	};

	cpu {
		/* CPU (a) */
		port { cpu_ep: endpoint { remote-endpoint = <&fe_ep>; } };
	};

	codec {
		/* Codec (b) */
		port {
			convert-rate = <48000>; /* (B) settings will be over written here */
			codec_ep: endpoint { remote-endpoint = <&be_ep>; }

	};

CPU3/CPU4 need to convert rate in this case.
This patch adds missing "convert-rate" setting sample for it.

The "convert-xxx" properties only have an effect for DPCM DAI links.
A DAI link is only created as DPCM if the device tree requires it;
part of this involves checking for the use of "convert-xxx" properties.

When the convert-sample-format property was added, the checks got out
of sync. A DAI link that specified only convert-sample-format but did
not pass any of the other DPCM checks would not go into DPCM mode and
the convert-sample-format property would be silently ignored.

Fix this by adding a function to do the "convert-xxx" property checks,
instead of open-coding it in simple-card and audio-graph-card. And add
"convert-sample-format" to the check function so that DAI links using
it will be initialized correctly.

Parse "convert-sample-format" DT binding and fixup the sample format
as applicable. This is similar to the existing "convert-channels" and
"convert-rate" properties for channels and rate fixup respectively.
