This change provides access to IOE through P2SB Sideband interface for
Meteor Lake TCSS functions of pad configuration and Thunderbolt
authentication. There is a policy of locking the P2SB access at the end
of platform initialization. The tbt_authentication is read from IOM
register through IOE P2SB at early silicon initialization phase and its
usage is deferred to usb4 driver.
