The Exar XR17V354 has 4 com ports that have a 256-byte FIFO, use a
frequency of 125Mhz, and have a unique sleep register. A custom
interrupt handler is setup in puc for these ports so it can check a
register which reports which ports triggered the interrupt, rather
than having to run comintr for every port every time.
