Add devicetree binding schema for the media I/O block implemented on Socionext Uniphier SoCs. This block is implemented on LD4, sLD8, Pro4, and LD11 SoCs. Media I/O block implemented on Socionext UniPhier SoCs is an integrated component of the stream type peripherals including SD, USB2.0, eMMC, and MIO-DMAC. Media I/O block has a common logic to control the component.
