mb/google/volteer: Add PMC.MUX.CONx devices to devicetree for Volteer 

Volteer's MUX connections are known, and can now be described in ACPI
tables. Port 1 has the only oddity, with SBU lines staying fixed in the
CC1 orientation.

TEST=Dump SSDT tables on Volteer, and confirm (coalesced for brevity):

Scope (\_SB.PCI0.PMC)
{
        Device (MUX)
        {
                Name (_HID, "INTC105C")
                Device (CON0)
                {
                        Name (_ADR, 0)
                        Name (_DSD, Package() {
                                Package () { "usb2-port-number", 9 },
                                Package () { "usb3-port-number", 1 },
                        })
                }
		Device (CON1)
		{
			Name (_ADR, 1)
                        Name (_DSD, Package() {
				Package () { "usb2-port-number", 4 },
                                Package () { "usb3-port-number", 2 },
                                Package () { "sbu-orientation", "normal" },
				...
		}
        }
}
