The Kconfig symbol NFC_LLCP was removed in commit 30cc4587 ("NFC: Move
LLCP code to the NFC top level diirectory"). But the reference to its
macro in this Makefile was only commented out. Remove it now.

And stop making it optional. LLCP is a fundamental part of the NFC
specifications and making it optional does not make much sense.

This is an implementation of ETSI TS 102 622 specification.
Many NFC chipsets use HCI as the host <-> target protocol on top of a
serial link like i2c.

This patch is an initial implementation for the NFC Logical Link Control
protocol. It's also known as NFC peer to peer mode.
This is a basic implementation as it lacks SDP (services Discovery
Protocol), frames aggregation support, and frame rejecion parsing.
Follow up patches will implement those missing features.
This code has been tested against a Nexus S phone implementing LLCP 1.0.

The NFC subsystem core is responsible for providing the device driver
interface. It is also responsible for providing an interface to the control
operations and data exchange.
