[PATCH] PCI Hotplug: fix up the sysfs file in the compaq pci hotplug driver

The Compaq PCI Hotplug driver was creating 2 sysfs files that contained
nothing but debug information, and had way more than "one value" in
them.  This patch converts the code to use debugfs for these files
instead.

Compile tested only.
