Tomasz Bursztyka d8dcf56334 cc2520: Enable hardware filtering all the time
This prevents false packets to get accepted/generated into RX fifo.
Also, this will make AUTOACK working properly, when enabled. For some
reasons FRMFILT1 and SRCMATCH need to get their reset values written at
initialization, or then hw filtering won't work. This behavior is not
documented as it seems.

Tomasz Bursztyka a1adbcb125 ieee802154: Replace the CC2520 driver with a new implementation
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.
