PATCH 2/2 Add a driver for the Winbond WPCD376I Consumer IR hardware

Add a driver for the the Consumer IR (CIR) functionality of the Winbond WPCD376I chipset (found on e.g. Intel DG45FC motherboards).

Changes since the first version:

o converted from an ACPI to a PNP driver using a patch provided by Bjorn Helgaas <[email protected]>

Changes since the second version:

o misc fixes to the irqhandler after discovering that the FIFO enforces 16 levels (was a separate patch in the -mm tree)
o __devexit annotations
o KEY_NUMERIC_[0-9] instead of KEY_[0-9]
o EV_MSC/MSC_SCAN instead of "last_scancode" sysfs attr
o last three points based on feedback from Dmitry Torokhov <[email protected]>
