mainboard/intel/icelake_rvp: Do initial mainboard commit

Clone entirely from mainboard/intel/cannonlake_rvp
commit id: af89f49b83260a04dece84b34e97560fb85d29ae

List of changes on top off initial cannonlake_rvp clone
 1. Rename "Cannonlake" with "Icelake".
 2. Replace "cannonlake_rvp" with "icelake_rvp".
 3. Rename "cnl" with "icl".
 4. Remove unwanted SPD file, will add correct SPD with mainboard
    patches.
 5. Remove NHLT related implementation.
 6. Remove FSP configs, will add once FSP headers are available.
 7. Removed smihandler.c, will add later if needed.
