This is a complete new cc2520 driver for zephyr. Intention is to fit better within Zephyr device driver model. - It's (almost*) ready to be instanciated as many times as necessary - It's fully interrupt based on SFD and FIFOP (no pin polling) - It's nicer to other sub-systems (it sleeps, no busy-wait loop) - It still loosely complies to old legacy radio device driver model *: GPIO API needs to be fixed in order to accept multiple callbacks, as well as enabling callbacks to retrieve private data. Notes: - Hardware filtering does not work yet as the net stack, above, needs to provide the relevant information for it (src/dst ieee802154 extended addresses, short addresses...) - A embryo of generic functions (txpower, channel, addresses...) have been implemented but don't belong yet to any radio device driver model. Such new driver model will come afterwards (soon?) - SPI API would need to be improved to avoid as much as possible memcpy as well as spi_slave_select() call.
