dt-bindings: net: bluetooth: convert MT7622 Bluetooth to the json-schema

This helps validating DTS files. Introduced changes:
1. Dropped serial details from example
2. Added required example include

-MediaTek SoC built-in Bluetooth Devices
-==================================
-
-This device is a serial attached device to BTIF device and thus it must be a
-child node of the serial node with BTIF. The dt-bindings details for BTIF
-device can be known via Documentation/devicetree/bindings/serial/8250.yaml.
-
-Required properties:
-
-- compatible:  Must be
-                 "mediatek,mt7622-bluetooth": for MT7622 SoC
-- clocks:      Should be the clock specifiers corresponding to the entry in
-               clock-names property.
-- clock-names: Should contain "ref" entries.
-- power-domains: Phandle to the power domain that the device is part of
-
-Example:
-
-       btif: serial@1100c000 {
-               compatible = "mediatek,mt7622-btif",
-                            "mediatek,mtk-btif";
-               reg = <0 0x1100c000 0 0x1000>;
-               interrupts = <GIC_SPI 90 IRQ_TYPE_LEVEL_LOW>;
-               clocks = <&pericfg CLK_PERI_BTIF_PD>;
-               clock-names = "main";
-               reg-shift = <2>;
-               reg-io-width = <4>;

-               bluetooth {
-                       compatible = "mediatek,mt7622-bluetooth";
