ec/google/chromeec: Fill typec ssdt based on TCSS mux config

In platforms that use PDC<->PMC direct connection to perform mux
configuration, PDC directly communicates the type-c port info to PMC.
Therefore, kernel does not need to talk to EC and PMC for mux
configuration.

cros_ec_typec driver in kernel provides support for accessing the Type-C
information from Chrome OS EC. Now with TCSS using PDC<->OMC mux config,
this driver is not required to be loaded in kernel to get typec port
connector information. So do not create a USB Type-C control ACPI
device.

BUG=b:332383540
TEST=Build and boot to OS on brox. Check SSDT before and after this
patch for USB Type-C device ID.
