HOBL worked in my TGL RVP even without the necessary HW support, also
it worked in more than half of the TGL machines in CI so it is worthy
to enable it by default.
Even if link training fails with this new vswing table it will only
cause one additional link training, that is worthy the try to get the
additional power-savings.
