Changes to the build infrastructure to include the mrf24j40 driver
include/nuttx/spi/spi.h
Define a IEEE SPI device
include/nuttx/wireless/ieee802154/ieee802154_radio.h
This file defines the API of a IEEE 802.15.4 radio device, to be used by the future common MAC 802.15.4 layer
drivers/wireless/ieee802154/mrf24j40.c
drivers/wireless/ieee802154/mrf24j40.h
The main MRF24J40 IEEE 802.15.4 radio driver
include/nuttx/wireless/ieee802154/mrf24j40.h
This file allows instanciation of the MRF24j40 driver from board configurations

* functions (i.e., MRF24J40 GPIO interrupts).
