The patch exposes the available i2c busses on the PowerNV platform

The driver uses the platform device infrastructure to probe the busses
on the platform and registers them with the i2c driver framework.

This had major conflicts in the above files.
I've fixed it up but please check I did it correctly:
https://github.com/mpe/powerpc-merge/commits/pw/neelesh-i2c
It also doesn't build as a module:
$ grep CONFIG_I2C_OPAL .config
CONFIG_I2C_OPAL=m
$ make ...
...
ERROR: "opal_i2c_request" [drivers/i2c/busses/i2c-opal.ko] undefined!
Yeah, this needs to be exported.
I think for the same reason, "opal-rtc" is still waiting, plus awaiting
"ack" from
maintainers.
