soc/intel/tigerlake: Enable TCSS Muxes to disconnect mode during boot
TCSS muxes being left uninitialized during boot is causing some USB3
devices to downgrade to USB2 speed. To properly configure the Type C ports
the muxes should be set to disconnected state during boot so that the port
mapping of USB2/3 devices is properly setup prior to Kernel initializing
devices.
BUG=b:180426950
BRANCH=firmware-volteer-13672.B
TEST= Connected USB3 storage device and rebooted the system multiple
times to verify that devices were no longer downgrading to USB2 speed.
