Christophe Ricard ed6a2f3fb7 nfc: st-nci: Add support for acpi probing for i2c device.
Add support for acpi probing.
SMO2101 is used for st21nfcb
SMO2102 is used for st21nfcc

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