Subject: [PATCH] pinctrl: mediatek: mt8189: align register base names to
 dt-bindings ones

The mt8189-pinctrl driver requires to probe that a device tree uses
in the device node the same names than mt8189_pinctrl_register_base_names
array. But they are not matching the required ones in the
"mediatek,mt8189-pinctrl" dt-bindings, leading to possible dtbs check
issues. The mt8189_pinctrl_register_base_names entry order is also
different.
So, align all mt8189_pinctrl_register_base_names entry names and order
on dt-bindings.
