dt-bindings: pinctrl: rt2880: fix binding name, pin groups and functions

Deprecate the old property "ralink,rt2880-pinmux". Add the new property
"ralink,rt2880-pinctrl". The old property name was inaccurate as the
hardware block is called pinctrl across the Mediatek/Ralink architecture.

Current pin group and function bindings are for MT7621. Put bindings for
RT2880 instead.

Add me as a maintainer.
