Simplify driver implementation by using spi_dt_spec. Note that driver
has 2 SPI configurations, identical except the speed. For this reason,
the slow config is still kept in RAM and copied from the one obtained
via the SPI dt_spec macros. A better solution would be to have macros
that allow to override the SPI frequency, but this can be improved
later. Most internal helpers have been adjusted to accept a device
reference to make SPI (and future GPIO) transition easier.

Driver has dedicated workqueue for IRQ processing.
Submit work to dedicated workqueue intead of system workqueue.
It also fixes driver functionality when NET_TC_TX_COUNT is set to 0.

Replace all existing deprecated API with the recommended alternative.
Be aware that this does not address architectural errors in the use
of the work API.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

Since commit 5963ebaf33
("drivers: spi: CS configuration through devicetree")
the SPI GPIO CS flags are obtained from DT,
but the patch series has missed the necessary changes
for the ieee802154_dw1000 driver and decawave_dwm1001_dev board.

Add initial support for Decawave DW1000
IEEE 802.15.4-2011 UWB transceiver.
Driver has basic functionality. Additional functions such
as reading out timestamps and delayed TX were implemented
for test purposes, but also require support in the 802154
subsystem.
Register, sub-register, and defaults defines in the file
ieee802154_dw1000_regs.h are taken from the Decawave's
DW1000 driver for the Mynewt OS.
