mainboard/intel/kblrvp: Initial commit for Intel Kaby Lake RVP3
Add support for Kaby Lake RVP3.
Use kunimitsu at commit 028200f as base.
Kabylake RVP3 is based on Kabylake-Y with onboard Dual Channel
LPDDR3 DIMM.
* Update board name to kblrvp
* Remove fsp 1.1 specific code( As Kabylake uses fsp2.0)
* Remove board id function.
* Remove unused spd & add rvp3 spd file.
This is an initial commit does not have full support to boot.
Will add more CLs to boot Chrome OS with depthcharge.
