platform/chrome: cros_ec_typec: Make sure the USB role switch has PLD

The USB role switch does not always have the _PLD (Physical
Location of Device) in ACPI tables. If it's missing,
assigning the PLD hash of the port to the switch. That
should guarantee that the USB Type-C port mapping code is
always able to find the connection between the two (the port
and the switch).
