Subject: [PATCH v3] 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.

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

Change in v2:
* Remove changes of the formatting of addresses and add C-d-b tag for
Guodong
Change in v1:
* Capitalize First Letter of Sentences and rephrase the commit message
