ASoC: rt5645: Add ACPI-defined GPIO for ECS EF20 series 

Add the hp-detect gpio for ECS EF20 series laptops based on the
_CRS defined in DSDT table.

Method (_CRS, 0, NotSerialized)
{
  Name (SBUF, ResourceTemplate ()
  {
    I2cSerialBusV2 (0x001A, ControllerInitiated, 0x00061A80,
        AddressingMode7Bit, "\\_SB.PCI0.I2C2",
        0x00, ResourceConsumer, , Exclusive,
        )
    GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 0x0000,
        "\\_SB.GPO3", 0x00, ResourceConsumer, ,
        )
        {   // Pin list
            0x004F
        }
    GpioIo (Shared, PullDefault, 0x0000, 0x0000, IoRestrictionInputOnly,
        "\\_SB.GPO3", 0x00, ResourceConsumer, ,
        )
        {   // Pin list
            0x004F
        }
  })
  Return (SBUF) /* \_SB_.PCI0.I2C2.RTK2._CRS.SBUF */
