mainboard/intel: Add MinnowBoard 3
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 name changes. Special adaptations for MinnowBoard 3
mainboard will follow in separate commits.
