UPSTREAM: mb/google/zork: Add support for fingerprint device

This change adds support for fingerprint device in overridetree for
the following variants:
1. berknip
2. morphius
3. trembyle

Generates the following node in SSDT1:
    Scope (_SB.FUR1)
    {
        Device (CRFP)
        {
            Name (_HID, "PRP0001")  // _HID: Hardware ID
            Name (_UID, Zero)  // _UID: Unique ID
            Name (_DDN, "Fingerprint Reader")  // _DDN: DOS Device Name
            Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                Return (0x0F)
            }

                    "\_SB.GPIO", 0x00, ResourceConsumer, ,
                    )
                    {   // Pin list
                        0x0006
                    }
            })
            Name (_S0W, 0x04)  // _S0W: S0 Device Wake State
            Name (_PRW, Package (0x02)  // _PRW: Power Resources for Wake
            {
                0x0A,
                0x03
            })
            Name (_DSD, Package (0x02)  // _DSD: Device-Specific Data
            {
                ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") /* Device Properties for _DSD */,
                Package (0x01)
                {
                    Package (0x02)
                    {
                        "compatible",
                        "google,cros-ec-uart"
                    }
                }
