Since copying i2c-mpc.c to maintain support for the ppc architecture seems to 
be an issue; instead rework i2c-mpc.c to use CONFIG_PPC_MERGE #ifdefs to 
support both the ppc and powerpc architecture. When ppc is deleted in six 
months these #ifdefs will need to be removed.

Another rework of the i2c for powerpc device tree patch. This version 
implements standard alias naming only on the powerpc platform and only for the 
device tree names. The old naming mechanism of i2c_client.name,driver_name is 
left in place and not changed for non-powerpc platforms. This patch is fully 
capable of dynamically loading the i2c modules. You can modprobe in the i2c-mpc 
driver and the i2c modules described in the device tree will be automatically 
loaded. Modules also work if compiled in.

The follow on patch to module-init-tools is also needed since the i2c subsystem 
has never implemented dynamic loading.

The following series implements standard linux module aliasing for i2c modules 
on arch=powerpc. It then converts the mpc i2c driver from being a platform 
driver to an open firmware one. I2C device names are picked up from the device 
tree. Module aliasing is used to translate from device tree names into to linux 
kernel names. Several i2c drivers are updated to use the new aliasing.
