        src/sys/arch/x86/pci: ichlpcib.c

Log Message:
Disable gpio(4) attachment to ichlpcib(4) by default.

The GPIO lines on an ICH are usually connected to opaque platform-
defined functionality, and may be manipulated by the ACPI DSDT or other
mechanisms behind our backs.  In one instance, it was found this
in combiation with gpio_resume() sabotaged repeated suspend/resume cycles.

GPIO functionality can be enabled by setting ichlpcib_gpio_disable to 0,
for instance with `gdb -write`.
