mmc: sdhci-cadence: add Socionext UniPhier specific compatible string 



Add a Socionext SoC specific compatible (suggested by Rob Herring).

No SoC specific data are associated with the compatible strings for
now, but other SoC vendors may use this IP and want to differentiate
IP variants in the future.

Required properties:

- compatible: should be "cdns,sd4hc".

- compatible: should be one of the following:

    "cdns,sd4hc"               - default of the IP

    "socionext,uniphier-sd4hc" - for Socionext UniPhier SoCs

- reg: offset and length of the register set for the device.

- interrupts: a single interrupt specifier.

- clocks: phandle to the input clock.
