serial: 8250: add Moxa MUEx50 UART port type
Add a new 8250 port type for the Moxa MUEx50 UART and describe its basic
FIFO size and trigger characteristics in the 8250 port configuration
table.
The 8250_mxpcie driver sets UPF_FIXED_TYPE and uses PORT_MUEX50 so that
the generic 8250 core applies the correct defaults.
