NFC: Add Intel Fields Peak NFC solution driver

Fields Peak complies with the ISO/IEC 14443A/B, 15693, 18092,
and JIS X 6319-4. It is an NCI based controller.

RF Protocols supported:
 - NFC Forum Type 1 Tags (Jewel, Topaz)
 - NFC Forum Type 2 Tags (Mifare UL)
 - NFC Forum Type 3 Tags (FeliCa)
 - NFC Forum Type 4A (ISO/IEC 14443 A-4 106kbps to 848kbps)
 - NFC Forum Type 4B (ISO/IEC 14443 B-4 106kbps to 848kbps)
 - NFCIP in passive and active modes (ISO/IEC 18092 106kbps
   to 424kbps)
 - B’ (based on ISO/IEC 14443 B-2)
 - iCLASS (based on ISO/IEC 15693-2)
 - Vicinity cards (ISO/IEC 15693-3)
 - Kovio tags (NFC Forum Type 2)

The device can be enumerated using ACPI using the id INT339A.
The 1st GPIO is the IRQ and the 2nd is the RESET pin.
