usb: usb-acpi: Set port connect type of not connectable ports correctly

Ports with  _UPC (USB Port Capability) ACPI objects stating they are
"not connectable" are not wired to any connector or internal device.
They only exist inside the host controller.

These ports may not have an ACPI _PLD (Physical Location of Device)
object.

Rework the code so that _UPC is read even if _PLD does not exist, and
make sure the port->connect_type is set to "USB_PORT_NOT_USED" instead
of "USB_PORT_CONNECT_TYPE_UNKNOWN".

No bugs or known issues are reported due to possibly not parsing _UPC,
and thus leaving the port connect type as "unknown" instead of
"not used". Nice to have this fixed but no need to add it to stable
kernels, or urgency to get it upstream.
