Enable host TMGT and OCC and move up to other phase 3 content

A couple things to note with this commit.
- OCC will become active on Palmetto systems by default which will result in the system running in turbo mode
- OCC will not become active on Habanero by default, we are still working an issue where the second IPL will fail.   If you only need 1 IPL then you can enable via the config and the first IPL works fine with OCC loaded.
- There is an intermittent error log against IBSCOM which will come on Palmetto boots in istep 21, this has no adverse affect and a fix is on it's way
