Added support for PC104 16550 devices (TS-MULTI-104, TS-IRIDIUM, etc)
Modified 8250 to use /dev/ttyZ# instead of /dev/ttyS#.  Since the CPU currently creates a /dev/ttyS0 the 8250 driver will fail when it cannot create that same device.
Added ts4700_isa16550 driver to the default config for the TS-471X
