Intelrvp: Add baseboard for Intel RVPs

Intel-RVP supports Chrome EC via an Add In Card called as MECC
(Modular Embedded Controller Card). MECC has a standard spec
which defines pin routing and purpose of these pins. These MECC
pins are same across all the platforms hence we can have a baseboard
for Intel-RVPs and reuse the code for RVP board specific codes.

Chrome MECC spec is standardized for Icelake and successor RVPs hence
this baseboard code is applicable to Icelake and its successors only.

BUG=b:132061907
TEST=Using this baseboard implemented board code for ICLRVP, and
     it can boot all the way to Chrome OS.
BRANCH=none
