drivers/usb/pci_xhci: Add a driver to generate xHCI ACPI nodes

We can use xhci_for_each_ext_cap to inspect the xHC so we generate the
correct number of device nodes.

    Scope (\_SB.PCI0.PBRA)
    {
        Device (XHC1)
        {
            Name (_ADR, 0x0000000000000004)  // _ADR: Address
            Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                Return (0x0F)
            }

            Name (_PRW, Package (0x02)  // _PRW: Power Resources for Wake
            {
                0x1F,
                0x03
            })
            Device (RHUB)
            {
                Name (_ADR, Zero)  // _ADR: Address
                Device (HS01)
                {
                    Name (_ADR, 0x01)  // _ADR: Address
                }

                Device (HS02)
                {
                    Name (_ADR, 0x02)  // _ADR: Address
                }

                Device (SS01)
                {
                    Name (_ADR, 0x03)  // _ADR: Address
                }
            }

            Name (_S0W, Zero)  // _S0W: S0 Device Wake State
            Name (_S3W, 0x04)  // _S3W: S3 Device Wake State
            Name (_S4W, 0x04)  // _S4W: S4 Device Wake State
        }
    }

BUG=b:154756391
TEST=Boot trembyle and look at ACPI table. See all xHCI nodes.
