mainboard/intel/leafhill: initial leafhill board changes

This commit makes the initial changes to support the Intel Leaf Hill
CRB with Apollo Lake silicon. Memory parameters and some GPIOs are set.

The google/reef directory is used as a template, and the same IFWI
stitching process as reef is used to generate a bootable image.

Apollo Lake silicon requires a boot media region called IFWI which includes
assets such as CSE firmware, PMC microcode, CPU microcode, and boot
firmware.
