tty: serial: meson: introduce separate uart_data for S4 SoC family

Browse Source 
In order to use the correct devname value for the S4 SoC family, it
is imperative that we implement separate uart_data. Unlike the legacy
g12a architecture, the S4 architecture should employ the use of 'ttyS'
devname.
