The CPLD is the communications medium between the CPU and the XMOS
"Xena" event coprocessor. It provides a mailbox communication feature,
along with dual-port RAM to be used between the CPU and XMOS. Also, it
provides basic board stats as well, such as PCIe presence, JTAG signals,
and CPU fan speed reporting (in revolutions per second). Only fan speed
is implemented, as a sysctl.

Fix the build. Last minute splitting of the driver out to have a header before submitting, but didn't build test first.

Stash off the softc in the cdev. It might be helpful to *not* dereference a
NULL pointer.

Works on my X5000, and looks good to me (other than needing to add that missing newline in the license in both cases)
