John Zhao 4ead6b3367 soc/intel/tigerlake: Enable USB2 port reset message on Type-C ports 
USB3 is in CPU and USB2 in PCH on Tigerlake. Cross die messaging is
implemented between CPU and PCH through the IOSF SB bridge. a PCH xHCI
USB2 port reset event issued by the xHCI driver shall trigger a message
upstream to CPU to wake it from the low power state which allows a USB3
device that downgraded to USB2 to upgrade back to USB3.

BUG=b:176575892
TEST=Built and booted to kernel on Voxel board.
