[PATCH 2.6] Add PCI quirk for SMBus on the Toshiba Satellite A40

Hi all,

The Toshiba Satellite A40 laptop hides its SMBus device, much like a
number of Asus boards reputedly do. This prevents access to the LM90
hardware monitoring chip. This simple patch extends the PCI quirk used
for the Asus and HP systems to this Toshiba laptop.

Please consider for merge into the PCI subsystem,
thanks.
