Subject: [PATCH v5 1/7] dt-bindings: pinctrl: mediatek,mt6779-pinctrl: Pull pinctrl node changes from MT6795 document

From: Yassine Oudjana <y.oudjana@...tonmail.com>

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.
