mb/intel/coffeelake_rvp: Add support for new board coffeelake RVP
Add support for new board coffeelake RVP. This patch is a copy patch and copies entire coffeelake_rvp folder from cannonlake_rvp. Changes done on top of copy: 1. Change copyright year from 2017 to 2018 2. Rename Cannonlake to Coffelake whenever applicable 3. Update entries in Kconfig and Kconfig.name 4. Rename variant directories to match coffeelake boards Change-Id: Id37bfeb0ae51fd630fec96273216dbb2900782c7 Signed-off-by: Maulik V Vaghela <maulik.v.vaghela@intel.com> Reviewed-on: https://review.coreboot.org/27904 Reviewed-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-by: Naresh Solanki <naresh.solanki@intel.com> Reviewed-by: Lijian Zhao <lijian.zhao@intel.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
