mainboard/intel: add leafhill board directory

This commit adds the initial scaffolding for the Intel Leafhill CRB
with Apollo Lake silicon.

The google/reef directory is used as a template. This commit only
makes the minimum changes to Kconfig and Kconfig.name needed for
the build bot to not have issues.
