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.
