Log Message:
Deal with quirks / differences in OpenFirmware implementations'
interpreation of the i2c "reg" property by embedding knowledge
of those quicks directly, rather than forcing lots of drivers
to provide their own devhandle implementations.  We default to
assuming the Device Tree bindings, and tweak based on platform-
specific #ifdefs.

Start with __HAVE_OPENFIRMWARE_VARIANT_AAPL (all i2c "reg" properties
encode an address that's shifted left 1 bit to account for the R/W bit
that appears on the wire).
