This device also requires a voltage regulator which
should be defined in a board-specific maner. An example
dts snipped follows.

/ {
	fixedregulator1v8: fixedregulator at 0 {
		compatible = "regulator-fixed";
		regulator-name = "fixed-1.8V";
		regulator-min-microvolt = <1800000>;
		regulator-max-microvolt = <1800000>;
	};
};

&mmcif {
	vmmc-supply = <&fixedregulator1v8>;
	vqmmc-supply = <&fixedregulator1v8>;
};

v2
* Removed SDHI intitialisation as the driver needs updating first
* Moved MMC DT from sh73a0.dtsi to sh73a0-reference.dtsi
  as it is not appropriate for use by sh73a0-kzm9g.dts yet.
  This is because sh73a0-kzm9g.dts and board-kzm9g.c use
  both the GIC and INTC interrupt controllers to provide
  access to a rich set of devices. This is achieved by initilising
  the interrupt controllers using C code. Work on allowing the INC
  controller to be initialised using DT is in progress, however,
  until that is complete only GIC may be initialised using DT.
* Add extra entries to clock-sh73a0.c:lookups[] and
  remove auxdata. Ultimtely the clocks will be described
  in DT, but the code isn't there yet.
