soc/intel/tigerlake: Update TCSS for SW CM support
This change adds support for SW CM. Add Operating System Capabilities
(_OSC) method to enable USB/DisplayPort/Inter-domain USB4 Internet
Protocol tunneling and enable PCIe tunneling as well. Remove Connect
Topology(CNTP) command because kernel driver directly works with SW CM
Thunderbolt firmware. Update _DSD method for USB4 support across XHCI
and PCIe root ports.
BUG=b:140645231
TEST=Check Type C device all ports connection/enumeration with SW CM.
