Dino Li 4d9dfa159b it8380dev: add ec2i control module
Add EC2I control module for emulation board.
The EC2I bridge enables the EC to access the host controlled
module registers (e.g., host configuration module(PNPCFG) and SWUC)

Signed-off-by: Dino Li <dino.li@ite.com.tw>

BRANCH=none
BUG=none
TEST=EC2I read: Read a logical device page, the results are correctly.
     EC2I write: Initialize PNPCFG success.
