dt-bindings: reset: convert Atmel/Microchip reset controller to YAML

Its subnodes can be:

- watchdog: compatible should be "atmel,at91rm9200-wdt"

RSTC Reset Controller required properties:

- compatible: Should be "atmel,<chip>-rstc".

  <chip> can be "at91sam9260", "at91sam9g45", "sama5d3" or "samx7"

  it also can be "microchip,sam9x60-rstc"

- reg: Should contain registers location and length

- clocks: phandle to input clock.

Example:

	rstc@fffffd00 {

		compatible = "atmel,at91sam9260-rstc";

		reg = <0xfffffd00 0x10>;

		clocks = <&clk32k>;

	};

RAMC SDRAM/DDR Controller required properties:

- compatible: Should be "atmel,at91rm9200-sdramc", "syscon"

			"atmel,at91sam9260-sdramc",
