[PATCH v3] 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.
We add jedec-flash to list of compatible because one board (gemini-dlink-dns-313.dts) needs it.
See commit a10d862e585e ("ARM: dts: Fix the DNS-313 flash compatible")
The flash on the DNS-313 needs to be probed as JEDEC, it does not conform to the common CFI standard.

-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 at 30000000 {
- compatible = "cortina,gemini-flash", "cfi-flash";
- reg = <0x30000000 0x01000000>;
- syscon = <&syscon>;
- bank-width = <2>;
