[PNPACPI] clean excluded_id_list[]
Clean the blacklist. Battery, Button, Fan have no _CRS and can be removed. PCI root is in pnpbios and is harmless. Cc: Adam Belay <ambx1@neo.rr.com> Cc: "Li, Shaohua" <shaohua.li@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Len Brown <len.brown@intel.com>
