NFC: Export new attributes sensb_res and sensf_res

Export new attributes sensb_res for tech B and sensf_res
for tech F in the target info (returned as a response to
NFC_CMD_GET_TARGET).
The max size of the attributes nfcid1, sensb_res and sensf_res
is exported to user space though include/linux/nfc.
