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.

The Microchip 23K256 is a 256 Kbit (32 Kbyte) serial SRAM with an
14
+
SPI interface,supporting clock frequencies up to 20 MHz. It features
15
+
a 32-byte page size for writes and supports byte, page, and
16
+
sequential access modes.
