soc/intel/icelake: Initial SoC commit
Clone entirely from Cannonlake commit id: af89f49b83260a04dece84b34e97560fb85d29ae
List of changes on top off initial cannonlake clone 1. Replace "Cannonlake" with "Icelake" 2. Replace "cnl" with "icl" 3. Replace "cnp" with "icp" 4. Rename structrue based on Cannonlake with Icelake 5. Remove and clean below files 5.a. All NHLT blobs and related files. 5.b. remove cnl_memcfg_init.c file, will be added later. 5.c. Remove vr_config.c, this is WIP. 5.d. Clean up upd override in fsp_params.c, will be added once FSP available.
Ice Lake specific changes will follow in subsequent patches.
