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.
