NFC: Select CRC_CCITT for SHDLC link layer of HCI based drivers

The SHDLC link layer of HCI based drivers uses CRC-CCITT and thus
needs to select that kernel option.

Otherwise it ends up with this linking error:

net/built-in.o: In function `nfc_shdlc_add_len_crc':
net/nfc/hci/shdlc.c:113: undefined reference to `crc_ccitt'
