Subject: [PATCH v2] dt-bindings: mtd: drop mtd/cortina,gemini-flash.txt

Drop mtd/cortina,gemini-flash.txt since it is nearly already handled by
Documentation/devicetree/bindings/mtd/mtd-physmap.yaml.

-Flash device on Cortina Systems Gemini SoC
-
-This flash is regular CFI compatible (Intel or AMD extended) flash chips with
-some special bits that can be controlled by the machine's system controller.
-
-Required properties:
-- compatible : must be "cortina,gemini-flash", "cfi-flash";
-- reg : memory address for the flash chip
-- syscon : must be a phandle to the system controller
-- bank-width : width in bytes of flash interface, should be <2>
-
-For the rest of the properties, see mtd-physmap.yaml.
-
-The device tree may optionally contain sub-nodes describing partitions of the
-address space. See partition.txt for more detail.
-
-Example:
-
-flash@...00000 {
-	compatible = "cortina,gemini-flash", "cfi-flash";
-	reg = <0x30000000 0x01000000>;
-	syscon = <&syscon>;
-	bank-width = <2>;
