dt-bindings: mips: convert Ralink SoCs and boards to schema

Ralink MIPS SoC device tree bindings

1. SoCs

Each device tree must specify a compatible value for the Ralink SoC

it uses in the compatible property of the root node. The compatible

value must be one of the following values:

  ralink,rt2880-soc

  ralink,rt3050-soc

  ralink,rt3052-soc

  ralink,rt3350-soc

  ralink,rt3352-soc

  ralink,rt3883-soc

  ralink,rt5350-soc

  ralink,mt7620a-soc

  ralink,mt7620n-soc

  ralink,mt7628a-soc

  ralink,mt7688a-soc

2. Boards

GARDENA smart Gateway (MT7688)

This board is based on the MediaTek MT7688 and equipped with 128 MiB

of DDR and 8 MiB of flash (SPI NOR) and additional 128MiB SPI NAND

storage.

------------------------------

Required root node properties:

- compatible = "gardena,smart-gateway-mt7688", "ralink,mt7688a-soc",

		"ralink,mt7628a-soc";
