Hello build bot (Jenkins), Christian Walter, Angel Pons, Lean Sheng Tan,

mb/prodrive/atlas: retrieve and apply boot-options from SMMSTORE

This patch retrieves boot-options (for example Hyperthreading)
from the SMMSTORE and applies them in the FSP-M and FSP-S and
also in mainboard.c (Powerstate after G3).

In order to do that, the patch was built on top of a series of patches
coming from Patrick Rudolph, which allows us to read Efi-Variables from
the SMMSTORE. This driver serves as a backend for option.h

Our EDK-II payload is responsible for setting up required efivars
and offering a user interface for changing them.
