pinctrl: mediatek: pinctrl-mtk-common-v2: Mark 'mtk_default_register_base_names' as __maybe_unused

Browse source 
Not all sourcefiles which end up including pinctrl-mtk-common-v2.h make use
of 'mtk_default_register_base_names' and there is nowhere we can place the
definition to void the need for __maybe_unused except its own headerfile,
which seems like overkill.  So instead we tell the compiler that it's okay
for it to be unused by some of the consumers.

Fixes the following W=1 kernel build warning(s):
