[PATCH v2] powerpc/pasemi: Remove hardcoded bus numbers on smbus

[Darren Stevens]

The pasemi smbus controller uses PCI_FUNC(dev->devfn) to define which
number bus to attach to, however this fails when something else is 
probed first, for example an ATI Radeon graphics card will claim 9 or
10 busses, including the ones the pasemi wants.
Patch the driver to call i2c_add_adapter rather than
i2c_add_numbered_adapter.

  v2 - remove unnecessary smbus->adapter.nr initialisation.
