drivers: uart: ns16550: Clean up Kconfig dependency usage

Browse source 
Use a dependency block instead of specifying a UART_NS16550 dependency
for each individual opton. This doesn't save many lines right now, but
may do so once more options are added.

In some case, e.g. ARC HS Development kit, the peripheral space of ns
16550 (DesignWare UART) only allows word access, byte access will raise
exception.
