[PATCH 4/9] Display VERSION partition info on BMC machines

Tue Dec 15 14:15:25 AEDT 2015
On supported platforms read the VERSION partition on startup and display
the available versions strings in the System Information screen.
This adds a skeleton hostboot.c to support possible additional BMC
platform support.
