Subject: [PATCH] pinctrl: mediatek: mt8196: align register base names to
 dt-bindings ones

The mt8196-pinctrl driver requires to probe that a device tree uses
in the device node the same names than mt8196_pinctrl_register_base_names
array. But they are not matching the required ones in the
"mediatek,mt8196-pinctrl" dt-bindings, leading to possible dtbs check
issues.
So, align all mt8196_pinctrl_register_base_names entries on dt-bindings
ones.
