soc/intel/alderlake: Enable USB2 port reset message on Type-C ports

This change is added to address the issue of USB3 ports downgrading to
high speed during low power modes and not returning back to super speed.

The patch enables port reset event on USB2 ports. This event is
is passed to USB3 upstream ports to upgrade back to super speed (USB3)
after a downgrade during low power state

BUG=b:193287279
TEST=Built coreboot on Gimble and tested type A pen drive detects as
super speed device
