This driver adds sysfs files that allow the BMC userspace to configure
how UARTs and physical serial I/O ports are routed.
Tested: Checked correct behavior (both read & write) on TYAN S7106
board by manually changing routing settings and confirming that bits
flow as expected. Tested for UART1 and UART3 as this board doesn't have
the other UARTs wired up in a testable way.
