Add Intel Whitetip Mountain 2 mainboard
This is mostly a copy of Whitetip Mountain 1 with specific GPIO
map for this Customer Reference Board (CRB).
This mainboard currently has basic funcionality and is able to
boot a Linux Kernel but many of the new Haswell ULT specific
devices are not yet enabled.
