The way we currently handle direction finding extension (DFE) support
on Nordic nRF5 controllers relies on required devicetree properties
related to DFE in the "nordic,nrf-radio" node.
That doesn't make sense on radios without DFE support, though.
Any .dtsi for an SoC without DFE support which has such a node would
require extraneous DFE related properties like dfe-antenna-num.
Instead of making the properties required, mark them optional. We
indicate the presence of DFE support via a new 'dfe-supported' boolean
property which the SoC .dtsi files can set (or not) depending on
support.
This gives us the opportunity to do some cleanup in the Kconfig,
removing CONFIG_HAS_HW_NRF_RADIO_BLE_DF since we know from the
devicetree whether DFE support is available.
Handle that change appropriately in radio_df.c. This gives us an
opportunity to improve readability in the devicetree-related macro
magic in that file.
