dt-bindings: soc: socionext: Add UniPhier media I/O block
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.
