commit a459297e14c8f3bc1d48586728d552da6bc37fba
Author: Brenton Dong <brenton.m.dong at intel.com>

intel/minnow3: Add new mainboard
This commit adds the initial scaffolding for the MinnowBoard 3
with Apollo Lake silicon.
This mainboard is based on Intel's Leafhill CRB with Apollo Lake
silicon. In a first step, it concerns only a copy of intel/leafhill
directory with minimum changes. Special adaptations for MinnowBoard 3
mainboard will follow in separate commits.
