ASoC: dt-bindings: wlf,wm8994: Convert to dtschema

Convert the Wolfson WM1811/WM8994/WM8958 audio codecs bindings to DT
schema.

Changes against original binding:
1. Add missing LDO1VDD-supply and LDO2VDD-supply.
2. Use "gpios" suffix for wlf,ldo1ena and wlf,ldo2ena (Linux kernel's
   gpiolib already looks for both variants).
3. Do not require AVDD1-supply and DCVDD-supply, because at least on
   Arndale board with Exynos5250 these are being supplied by internal
   LDOs.

-WM1811/WM8994/WM8958 audio CODEC
-
-These devices support both I2C and SPI (configured with pin strapping
-on the board).
-
-Required properties:
-
-  - compatible : One of "wlf,wm1811", "wlf,wm8994" or "wlf,wm8958".
-
-  - reg : the I2C address of the device for I2C, the chip select
-          number for SPI.
-
-  - gpio-controller : Indicates this device is a GPIO controller.
-  - #gpio-cells : Must be 2. The first cell is the pin number and the
-    second cell is used to specify optional parameters (currently unused).
-
-  - power supplies for the device, as covered in
-    Documentation/devicetree/bindings/regulator/regulator.txt, depending
-    on compatible:
-    - for wlf,wm1811 and wlf,wm8958:
-      AVDD1-supply, AVDD2-supply, DBVDD1-supply, DBVDD2-supply, DBVDD3-supply,
-      DCVDD-supply, CPVDD-supply, SPKVDD1-supply, SPKVDD2-supply
-    - for wlf,wm8994:
-      AVDD1-supply, AVDD2-supply, DBVDD-supply, DCVDD-supply, CPVDD-supply,
-      SPKVDD1-supply, SPKVDD2-supply
-
-Optional properties:
-
-  - interrupts : The interrupt line the IRQ signal for the device is
-    connected to.  This is optional, if it is not connected then none
-    of the interrupt related properties should be specified.
-  - interrupt-controller : These devices contain interrupt controllers
-    and may provide interrupt services to other devices if they have an
-    interrupt line connected.
-  - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
-    The first cell is the IRQ number.
-    The second cell is the flags, encoded as the trigger masks from
-    Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-
-  - clocks : A list of up to two phandle and clock specifier pairs
-  - clock-names : A list of clock names sorted in the same order as clocks.
-                  Valid clock names are "MCLK1" and "MCLK2".
-
-  - wlf,gpio-cfg : A list of GPIO configuration register values. If absent,
-    no configuration of these registers is performed. If any value is
-    over 0xffff then the register will be left as default. If present 11
-    values must be supplied.
-
-  - wlf,micbias-cfg : Two MICBIAS register values for WM1811 or
-    WM8958.  If absent the register defaults will be used.
-
-  - wlf,ldo1ena : GPIO specifier for control of LDO1ENA input to device.
-  - wlf,ldo2ena : GPIO specifier for control of LDO2ENA input to device.
-
-  - wlf,lineout1-se : If present LINEOUT1 is in single ended mode.
-  - wlf,lineout2-se : If present LINEOUT2 is in single ended mode.
-
-  - wlf,lineout1-feedback : If present LINEOUT1 has common mode feedback
-    connected.
-  - wlf,lineout2-feedback : If present LINEOUT2 has common mode feedback
-    connected.
-
-  - wlf,ldoena-always-driven : If present LDOENA is always driven.
-
-  - wlf,spkmode-pu : If present enable the internal pull-up resistor on
-    the SPKMODE pin.
-
-  - wlf,csnaddr-pd : If present enable the internal pull-down resistor on
-    the CS/ADDR pin.
-

-  * IN1LP
-  * IN2LN
-  * IN2LP:VXRN
-  * IN1RN
-  * IN1RP
