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
