[PATCH 27/54] dt-bindings: net: wireless: Convert ESP ESP8089 binding to a schema

The ESP8089 Wireless Chip is supported by Linux (through an out-of-tree
driver) thanks to its device tree binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

-This node provides properties for controlling the ESP8089 wireless device.
-The node is expected to be specified as a child node to the SDIO controller
-that connects the device to the system.
-
-Required properties:
-
- - compatible : Should be "esp,esp8089".
-
-Optional properties:
- - esp,crystal-26M-en: Integer value for the crystal_26M_en firmware parameter
-
-Example:
-
-&mmc1 {
- #address-cells = <1>;
- #size-cells = <0>;
-
- vmmc-supply = <&reg_dldo1>;
- mmc-pwrseq = <&wifi_pwrseq>;
- bus-width = <4>;
- non-removable;
-
- esp8089: sdio_wifi@1 {
- compatible = "esp,esp8089";
- reg = <1>;
- esp,crystal-26M-en = <2>;
- };
