isp driver - sysctl controls missing

Actually, it looks to be just a documentation "bug".

Further reading of the source shows that in isp_pci.c, it now just
reads the sysctl variables as driver hints (set in /boot/device.hints).

That's probably the better way to do it since the values don't get
changed once the system is booted.

Good to see it's still modifiable!

Cheers,
  Ross.
