ec/google/chromeec: Add .scan_bus() callback for Chrome EC device 

This change adds scan_static_bus() as .scan_bus() callback for Chrome EC
device which allows scanning of devices sitting behind the EC using
the topology provided by mainboard's devicetree.cb.

BUG=b:154290952
TEST=Verified with follow-up changes that devices behind EC are scanned
correctly.
