Christophe Ricard 60cd6d8931 nfc: st-nci: Add support for acpi probing for spi device.
Add support for acpi probing.
SMO2101 is used for st21nfcb

It has been tested with the following acpi node on Minnowboard:
Note: Remove uicc-present or ese-present Package if one of them is not
supported.

Device (NFC1)

	Name (_ADR, Zero)  // _ADR: Address
	Name (_HID, "SMO2101")  // _HID: Hardware ID
	Name (_CID, "SMO2101")  // _CID: Compatible ID
	Name (_DDN, "SMO NFC")  // _DDN: DOS Device Name
	Name (_UID, One)  // _UID: Unique ID
	Name (_DSD, Package (0x02)
	{
		/* Device Properties for _DSD */

		Package (0x02)
		{
			Package (0x02) { "uicc-present", 1 },
			Package (0x02) { "ese-present", 1 }
		}
	})
	Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
	{

		Return (SBUF) /* \_SB_.SPI1.NFC1._CRS.SBUF */
	}
	Method (_STA, 0, NotSerialized)  // _STA: Status
