NFC: fix header file kernel-doc warnings

NFC: fix header file kernel-doc warnings

Repair some of the comments:
- use the correct enum names
- don't use "/**" for a non-kernel-doc comment

to fix these warnings:

Warning: include/uapi/linux/nfc.h:127 Excess enum value
 '@NFC_EVENT_DEVICE_DEACTIVATED' description in 'nfc_commands'
Warning: include/uapi/linux/nfc.h:204 Excess enum value
 '@NFC_ATTR_APDU' description in 'nfc_attrs'
Warning: include/uapi/linux/nfc.h:302 expecting prototype for Pseudo().
 Prototype was for NFC_RAW_HEADER_SIZE() instead
