gma tgl: Factor TC ownership/connection handling out
The ownership and connection handling differs for Alder Lake. It uses
kind of the same procedures with different registers and layouts. Move
things into a sub-package `TC.Ownership', to allow alternative imple-
mentations.
We have to share some register definitions with the sub-package, hence
move related things into the private part of `TC'.
