Subject: [PATCH v7 1/7] dt-bindings: pinctrl: mediatek,mt6779-pinctrl: Pull pinctrl node changes from MT6795 document

mediatek,pinctrl-mt6795.yaml has different node name patterns which match
bindings of other MediaTek pin controllers, ref for pinmux-node.yaml which
has a description of the pinmux property, as well as some additional
descriptions for some pin configuration properties. Pull those changes
into mediatek,mt6779-pinctrl.yaml and adjust the example DTS to match in
preparation to combine the MT6795 document into it.

The only DT that currently gets affected by these changes is mt6797.dtsi.
It is modified to match the new bindings in a following patch.
