mb/google/fatcat: Add minimal code support for fatcat

This patch adds initial code block required to build google/fatcat
board with Intel Meteor Lake Silicon. Later after the initial board
power-on is successful, we shall switch to Panther Lake silicon to
build the google/fatcat reference design.

BUG=b:347669091
TEST=Able to build the google/fatcat and able to hit power-on reset
using Intel Meteor Lake SoC platform.
