PNP: skip UNSET MEM resources as well as DISABLED ones
Bjorn Helgaas [Thu, 5 Jun 2008 16:32:23 +0000 (10:32 -0600)]
We don't need to reserve "unset" resources.  Trying to reserve
them results in messages like this, which are ugly but harmless:

    system 00:08: iomem range 0x0-0x0 could not be reserved

Future PNP patches will remove use of IORESOURCE_UNSET, but
we still need it for now.
