Convert the Maxim Integrated MAX98925/MAX98926/MAX98927 speaker
amplifier bindings to DT schema format.  Changes during conversion: add
sound-dai-cells, already used by DTS.

Ryan,
As original author, I added you as bindings maintainer. Is that okay or
maybe someone else from Maxim should take care about the bindings?

-Maxim Integrated MAX98925/MAX98926/MAX98927 Speaker Amplifier
-
-This device supports I2C.
-
-Required properties:
-
-  - compatible : should be one of the following
-    - "maxim,max98925"
-    - "maxim,max98926"
-    - "maxim,max98927"
-
-  - vmon-slot-no : slot number used to send voltage information
-                   or in inteleave mode this will be used as
-                   interleave slot.
-                   MAX98925/MAX98926 slot range : 0 ~ 30,  Default : 0
-                   MAX98927 slot range : 0 ~ 15,  Default : 0
-
-  - imon-slot-no : slot number used to send current information
-                   MAX98925/MAX98926 slot range : 0 ~ 30,  Default : 0
-                   MAX98927 slot range : 0 ~ 15,  Default : 0
-
-  - interleave-mode : When using two MAX9892X in a system it is
-                   possible to create ADC data that that will
-                   overflow the frame size. Digital Audio Interleave
-                   mode provides a means to output VMON and IMON data
-                   from two devices on a single DOUT line when running
-                   smaller frames sizes such as 32 BCLKS per LRCLK or
-                   48 BCLKS per LRCLK.
-                   Range : 0 (off), 1 (on),  Default : 0
-
-  - reg : the I2C address of the device for I2C
-
-Optional properties:
-  - reset-gpios : GPIO to reset the device
-
-Example:
-
-codec: max98927@3a {
-   compatible = "maxim,max98927";
-   vmon-slot-no = <0>;
-   imon-slot-no = <1>;
-   interleave-mode = <0>;
-   reg = <0x3a>;
