[patch 04/28] PNP: add pnp_resource_type_name() helper function

[Bjorn Helgaas <bjorn.helgaas@hp.com>]

This patch adds a "pnp_resource_type_name(struct resource *)" that
returns the string resource type.  This will be used by the sysfs
"show resources" function and the debug resource dump function.
