superio/nuvoton: Factor out equivalent Kconfig option

There's no need to have multiple Kconfig symbols which do the same
thing. Introduce `SUPERIO_NUVOTON_COMMON_COM_A` and update boards to use
the new symbol. To preserve alphabetical order in mainboard Kconfig,
place the new symbol above the Super I/O symbol (instead of below).
