mainboard/intel/harcuvar: Add support for Intel Harcuvar CRB

The Harcuvar CRB is a reference platform of Intel Atom C3000 SoC
("Denverton" and "Denverton-NS") for the communications segment/market.
The MohonPeak coreboot was used as the starting template with
additions/modifications from other Intel Apollo Lake/Skylake coreboot.
Tested with TianoCore payload (UDK2015) and Poky (Yocto
Project Reference Distro) 2.0 with kernel 4.1.8 booted from
SATA drive and external USB pendrive.
