Required properties:
- compatible: should be one of the following:
    "snps,dwcmshc-sdhci"
- reg: offset and length of the register set for the device.
- interrupts: a single interrupt specifier.
- clocks: Array of clocks required for SDHCI; requires at least one for
    core clock.
- clock-names: Array of names corresponding to clocks property; shall be
    "core" for core clock and "bus" for optional bus clock.

Example:
	sdhci2: sdhci@aa0000 {
		compatible = "snps,dwcmshc-sdhci";
		reg = <0xaa0000 0x1000>;
		interrupts = <GIC_SPI 21 IRQ_TYPE_LEVEL_HIGH>;
		clocks = <&emmcclk>;
		bus-width = <8>;
