Code update interface for powernv platform. This provides
sysfs interface to pass new image, validate, update and
commit images.
This patch includes:

- opal_update_flash()
- Create below sysfs files under /sys/firmware/opal
- image : Interface to pass new FW image

during system reboot time.

I have kept version number to keep this list similar to what
PAPR is defined.
