dt-bindings: pinctrl: mediatek: mt7620: split binding

The MT7628 and MT7688 SoCs contain different pin muxing information,
therefore, should be split. This can be done now that there are compatible
strings to distinguish them from other SoCs.

Split the schema out to mediatek,mt76x8-pinctrl.yaml.

Remove mediatek,mt76x8-pinctrl from mt7620.

-  MediaTek MT7620 pin controller for MT7620, MT7628 and MT7688 SoCs.
+  MediaTek MT7620 pin controller for MT7620 SoC.
   The pin controller can only set the muxing of pin groups. Muxing individual
   pins is not supported. There is no pinconf support.

+  MediaTek MT76X8 pin controller for MT7628 and MT7688 SoCs.
+  The pin controller can only set the muxing of pin groups. Muxing individual
