soc/intel/common/tcss: Configure USB-C ports with attached devices

Inspect all type-C USB ports, check if there is a USB device attached,
and if so, send the connection request to the PMC. This allows for any
attached USB2/USB3 devices to be used for booting by the payload.

Since this functionality is only needed by ChromeOS devices with TCSS
running upstream coreboot, introduce a new Kconfig to guard its use.
Boards needing it will select it in subsequent commits.

TEST=tested with rest of patch train
