None of the existing models is suitable for use with
RISC-V virt guests, and we don't want information about
the serial console to be missing from the XML.
The name is based on comments in qemu/hw/riscv/virt.c:
RISC-V machine with 16550a UART and VirtIO MMIO
and in qemu/hw/char/serial.c:
QEMU 16550A UART emulation
along with the output of dmesg in the guest:
Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled
10000000.uart: ttyS0 at MMIO 0x10000000 (irq = 13,
base_baud= 230400) is a 16550A
