dt-bindings: pinctrl: mt8186: Fix 'reg-names' for pinctrl nodes

The mt8186 contains 8 GPIO physical address bases that correspond to
the 'reg-names' of the pinctrl driver. The 'reg-names' entries in
bindings are ordered incorrectly, though. The system crashes due of an
erroneous address when the regulator initializes.

We fix the 'reg-names' for the pinctrl nodes and the pinctrl-mt8186
example in bindings.
