Current QMSI SPI API does not handle asymmetric tx/rx buffers, and thus
it's up to cc2520 driver to manage the tx dummy bytes.

-EIO is an error code for operationnal error, not about invalid
argument.

DEV_* error codes are deprecated and should not be used anymore. This
patch replaces DEV_* occurrences by the corresponding errno.h code,
according to the error code conventions.

Adapting CC2520 driver to use the new callback format. That way, cc2520
will work on boards where FIFOP and SFD are hooked to a different GPIO
controller.

Disable reception and the oscillator as well when stopping. Revert
when starting.

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.

For hw filtering and autoack to work, all the information should be
properly set in the chip.
That's a fix for the legacy radio/net API. From original code, these
were set from the application which is bad. But setting it from the
driver is not any better. ieee802154 and net stack should know what to
do, that will be fixed in the future.

Because the random number generator is very dumb at the moment,
the generated MAC address has always last byte set to 0.
The MAC address is used when generating IPv6 address.
In order to avoid IPv6 address collision, swap the last four
bytes of the MAC address so that the most random data is
at the end of the MAC.

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.

ieee802154 is a more relevant name. Applying the change in
include/drivers as well.
