tty: serial: meson: apply ttyS devname instead of ttyAML for new SoCs

It is worth noting that the devname ttyS is a widely recognized tty name
and is commonly used by many uart device drivers. Given the established
usage and compatibility concerns, it may not be feasible to change the
devname for older SoCs. However, for new definitions, it is acceptable
and even recommended to use a new devname to help ensure clarity and
avoid any potential conflicts on lower or upper software levels.
