[V4,0/6] net: lorawan: Add LoRaWAN soft MAC module

Message

LoRaWAN(TM) is the MAC layer defined by LoRa Alliance(TM) over LoRa
devices.  LoRa is one of Low-Power Wide-Area Network (LPWAN) technology.

LoRaWAN networks typically are laid out in a star-of-stars topology in
which gateways relay messages between end-devices and a central network
server at the backend.  Gateways are connected to the network server via
standard IP connections while end-devices use single hop LoRa(TM) or FSK
communication to one or many gateways.

A LoRa network distinguishes between a basic LoRaWAN (named Class A) and
optional features (Class B, Class C ...):
* Bi-directional end-devices (Class A)
* Bi-directional end-devices with scheduled receive slots (Class B)
* Bi-directional end-devices with maximal receive slots (Class C)

This patch set add LoRaWAN class module implementing the stack,
especially the soft MAC, between socket APIs and LoRa device drivers.

socket APIs:
send and receive the data
------------------------------------------------------------------------
LoRaWAN class module implements soft MAC:
append the header/footer, encryption/decryption, timing slot and MAC
commands
------------------------------------------------------------------------
LoRa device drivers:
send and receive the messages for MAC layer
------------------------------------------------------------------------
LoRa devices

This module starts from simple and implements partial Class A
end-devices features defined in LoRaWAN(TM) Specification Ver. 1.0.2.
More features and complexity, for example regional parameters, confirmed
data messages, join request/accept messages for Over-The-Air Activation,
MAC commands ... will be added in the future.
