[PATCH v2 2/2] ASoC: dt-bindings: fsl-asoc-card: convert to YAML

Convert the fsl-asoc-card binding to YAML.

When testing dtbs_check, found below compatible strings
are not listed in document:

fsl,imx-sgtl5000
fsl,imx53-cpuvo-sgtl5000
fsl,imx51-babbage-sgtl5000
fsl,imx53-m53evk-sgtl5000
fsl,imx53-qsb-sgtl5000
fsl,imx53-voipac-sgtl5000
fsl,imx6-armadeus-sgtl5000
fsl,imx6-rex-sgtl5000
fsl,imx6-sabreauto-cs42888
fsl,imx6-wandboard-sgtl5000
fsl,imx6dl-nit6xlite-sgtl5000
fsl,imx6q-ba16-sgtl5000
fsl,imx6q-nitrogen6_max-sgtl5000
fsl,imx6q-nitrogen6_som2-sgtl5000
fsl,imx6q-nitrogen6x-sgtl5000
fsl,imx6q-sabrelite-sgtl5000
fsl,imx6q-sabresd-wm8962
fsl,imx6q-udoo-ac97
fsl,imx6q-ventana-sgtl5000
fsl,imx6sl-evk-wm8962
fsl,imx6sx-sdb-mqs
fsl,imx6sx-sdb-wm8962
fsl,imx7d-evk-wm8960
karo,tx53-audio-sgtl5000
tq,imx53-mba53-sgtl5000

So add them in yaml file to pass the test.

Also correct the 'dai-format' to 'format' in document.

For 'audio-routing', the items are not listed. Because
this fsl-asoc-card is generic driver, which supports several
codecs, if list all the items, there will be a long list.

-Freescale Generic ASoC Sound Card with ASRC support
-
-The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale
-SoCs connecting with external CODECs.
-
-The idea of this generic sound card is a bit like ASoC Simple Card. However,
-for Freescale SoCs (especially those released in recent years), most of them
-have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
-this is a specific feature that might be painstakingly controlled and merged
-into the Simple Card.
-
-So having this generic sound card allows all Freescale SoC users to benefit
-from the simplification of a new card support and the capability of the wide
-sample rates support through ASRC.
-
-Note: The card is initially designed for those sound cards who use AC'97, I2S
-      and PCM DAI formats. However, it'll be also possible to support those non
-      AC'97/I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as
-      long as the driver has been properly upgraded.
-
-
-The compatible list for this generic sound card currently:
- "fsl,imx-audio-ac97"
-
- "fsl,imx-audio-cs42888"
-
- "fsl,imx-audio-cs427x"
- (compatible with CS4271 and CS4272)
-
- "fsl,imx-audio-wm8962"
-
- "fsl,imx-audio-sgtl5000"
- (compatible with Documentation/devicetree/bindings/sound/imx-audio-sgtl5000.txt)
-
- "fsl,imx-audio-wm8960"
-
- "fsl,imx-audio-mqs"
-
- "fsl,imx-audio-wm8524"
-
- "fsl,imx-audio-tlv320aic32x4"
-
- "fsl,imx-audio-tlv320aic31xx"
-
- "fsl,imx-audio-si476x"
-
- "fsl,imx-audio-wm8958"
-
- "fsl,imx-audio-nau8822"
-
-Required properties:
-
-  - compatible		: Contains one of entries in the compatible list.
-
-  - model		: The user-visible name of this sound complex
-
-  - audio-cpu		: The phandle of an CPU DAI controller
-
-  - audio-codec		: The phandle of an audio codec
-
-Optional properties:
-
-  - audio-asrc		: The phandle of ASRC. It can be absent if there's no
-			  need to add ASRC support via DPCM.
-
-  - audio-routing	: A list of the connections between audio components.
-			  Each entry is a pair of strings, the first being the
-			  connection's sink, the second being the connection's
-			  source. There're a few pre-designed board connectors:
-			   * Line Out Jack
-			   * Line In Jack
-			   * Headphone Jack
-			   * Mic Jack
-			   * Ext Spk
-			   * AMIC (stands for Analog Microphone Jack)
-			   * DMIC (stands for Digital Microphone Jack)
-
-			  Note: The "Mic Jack" and "AMIC" are redundant while
-			        coexisting in order to support the old bindings
-				of wm8962 and sgtl5000.
-
-  - hp-det-gpio		: The GPIO that detect headphones are plugged in
-  - mic-det-gpio	: The GPIO that detect microphones are plugged in
-  - bitclock-master	: Indicates dai-link bit clock master; for details see simple-card.yaml.
-  - frame-master	: Indicates dai-link frame master; for details see simple-card.yaml.
-  - dai-format		: audio format, for details see simple-card.yaml.
-  - frame-inversion	: dai-link uses frame clock inversion, for details see simple-card.yaml.
-  - bitclock-inversion	: dai-link uses bit clock inversion, for details see simple-card.yaml.
-  - mclk-id		: main clock id, specific for each card configuration.
-
-Optional unless SSI is selected as a CPU DAI:
-
-  - mux-int-port	: The internal port of the i.MX audio muxer (AUDMUX)
-
-  - mux-ext-port	: The external port of the i.MX audio muxer
-
-Example:
-sound-cs42888 {
-	compatible = "fsl,imx-audio-cs42888";
-	model = "cs42888-audio";
-	audio-cpu = <&esai>;
-	audio-asrc = <&asrc>;
-	audio-codec = <&cs42888>;
-	audio-routing =
-		"Line Out Jack", "AOUT1L",
-		"Line Out Jack", "AOUT1R",
-		"Line Out Jack", "AOUT2L",
-		"Line Out Jack", "AOUT2R",
-		"Line Out Jack", "AOUT3L",
-		"Line Out Jack", "AOUT3R",
