Log Message:
Define __HAVE_OPENFIRMWARE_VARIANT_SUNW for sparc64 systems and handle
its OpenFirmware quirks with respect to i2c:

- "reg" property is 2 cells, the first one containing the channel the
  device is on, the second one containing the i2c device address.
- The i2c device address is shifted left 1 bit to account for the r/w
  bit on the wire.
