dt-bindings: mtd: microchip,mchp23k256: convert to DT schema 



Convert Microchip 23K256 SPI SRAM MTD binding to YAML format.
Changes during conversion:
- Remove "address-cells" and "size-cells" from properties and
  required sections as there is no child node for sram.

* MTD SPI driver for Microchip 23K256 (and similar) serial SRAM



Required properties:

- #address-cells, #size-cells : Must be present if the device has sub-nodes

  representing partitions.

- compatible : Must be one of "microchip,mchp23k256" or "microchip,mchp23lcv1024"

- reg : Chip-Select number

- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at



Example:



	spi-sram@0 {

		#address-cells = <1>;

		#size-cells = <1>;

		compatible = "microchip,mchp23k256";

		reg = <0>;

		spi-max-frequency = <20000000>;

	};

description:

  The Microchip 23K256 is a 256 Kbit (32 Kbyte) serial SRAM with an

  SPI interface,supporting clock frequencies up to 20 MHz. It features

  a 32-byte page size for writes and supports byte, page, and

  sequential access modes.
