[patch 1/2] Add a shutdown method to pnp drivers

The shutdown method is used by the winbond cir driver to setup the hardware for wake-from-S5. Changes since last version: the previous patch added a shutdown method to acpi drivers, the winbond cir driver is now a pnp driver so the shutdown method is added to pnp drivers instead. Patch by Bjorn Helgaas [off-list ref].
