tpm: st33zp24: Add support for acpi probing for spi device.

Add support for acpi probing. SMO3324 is used for st33zp24.
It has been tested with the following acpi node on Minnowboard:

Device (TPM1)
{
	Name (_ADR, Zero)  // _ADR: Address
	Name (_HID, "SMO3324")  // _HID: Hardware ID
	Name (_CID, "SMO3324")  // _CID: Compatible ID
	Name (_DDN, "SMO TPM")  // _DDN: DOS Device Name
	Name (_UID, One)  // _UID: Unique ID
	Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
	{
		Name (SBUF, ResourceTemplate ()
		{
			SpiSerialBus (0, PolarityLow, FourWireMode, 8,
				      ControllerInitiated, 4000000, ClockPolarityLow,
				      ClockPhaseFirst, "\\_SB.SPI1",
				      0x00, ResourceConsumer, ,)
			GpioInt (Edge, ActiveHigh, ExclusiveAndWake, PullNone, 0x0000,
				 "\\_SB.GPO2", 0x00, ResourceConsumer, ,)
			{       // Pin list
				0x0001
			}
			GpioIo (Exclusive, PullDefault, 0x0000, 0x0000, IoRestrictionOutputOnly,
				"\\_SB.GPO2", 0x00, ResourceConsumer, ,)
			{       // Pin list
				0x0002,
			}
		})
		Return (SBUF) /* \_SB_.SPI1.TPM1._CRS.SBUF */
	}
	Method (_STA, 0, NotSerialized)  // _STA: Status
	{
		Return (0x0F)
	}
}
