There are 8 GPIO physical address bases in mt8186, corresponding to the
items of 'reg-names' with the pinctrl driver. but the order of
'reg-names' is not correct. The mt8186 pinctrl driver would get the
wrong address, causing the system to restart when regulator initializes
. we fix 'reg-names' for pinctrl nodes and the pinctrl-mt8186 example
in bindings.

Fixes: 338e953f1bd1 ("dt-bindings: pinctrl: mt8186: add pinctrl file and binding document")
