Sat Feb 6 07:08:36 CET 2016
IvyBridge FSP package is built with a base address at 0xfff80000,
and does not use UPD data region. This adds basic FSP support.

Tested on link (ivybridge non-FSP)

- Drop patches which were already applied
- Rebase on top of u-boot-x86/master
- Change fsp files license from Intel to GPL-2.0+
