x86 intel: Add Firmware Interface Table support

Browse Source 
Haswell CPUs require a FIT table in the firmware. This commit
adds rudimentary support for a FIT table. The number of entries
in the table is based on a configuration option. The code only
generates a type 0 entry. A follow-on tool will need to be developed
to populate the FIT entries as well as checksumming the table.

Verified image has a FIT pointer and table when option is selected.
