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" },
...
}
}
}
