x86/PCI: make Broadcom CNB20LE driver EMBEDDED and EXPERIMENTAL 

This functionality is known to be incomplete, so discourage its use in
general-purpose kernels.

The only reason to use this driver is to support PCI hotplug on CNB20LE-
based machines that don't have ACPI, and there are very few such
systems.

	  Read the PCI windows out of the CNB20LE host bridge. This allows

	  PCI hotplug to work on systems with the CNB20LE chipset which do

	  There's no public spec for this chipset, and this functionality
