Tomasz Bursztyka 3587fe2fe3 drivers/ieee802154: Adapt cc2520 driver to new GPIO API
Update to use new API for GPIO pin configuration and operation.  Fix
invalid arithmetic on void pointer.  Mark all CC2520 GPIOs as required
in binding.

Tomasz Bursztyka 8ded57d3a2 drivers/ieee802154: Add support for Sub-GHz TI CC1200 chip
CC1200 is a sub-ghz chip supporting 6 ISM & SRD bands: 169, 433, 470,
868, 915 and 920 MHz, with features dedicated to IEEE 802.15.4(g).

Current driver enables CC1200 against actual IEEE 802.15.4 Soft-MAC. 'g'
version support in the Soft-MAC will follow later.

The chip itself is closer to a bare metal radio modem than to a usual
15.4 chip: up to the user to provide the right RF settings for the
carrier band. Such settings can be generaten through TI's SmartRF tool.

Hopefully, for channel selection, this driver will be clever enough to
compute the proper register change without any special input from the
user. This will work for all the bands supported by the chip.

Kumar Gala a509441210 net: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Tomasz Bursztyka ba90139cbd ieee802154: cc2520: Externalize how GPIOs are configured
Currently it's only possible to configure those GPIOs through
boards.<h/c> files and thus it's not relevant for board that do not
embed cc2520 but might get one wired to it, unlike
quark_se_c1000_devboard which directly embeds one cc2520.

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.
