cte_info_clear function is responsible for remove of CTE from
periodic advertising PDUs, including remove from optional chained
PDUs. The function uses subortinate function rem_cte_info_from_per_-
adv_chain to remove CTE from chained PDUs.
The rem_cte_info_from_per_adv_chain had pdu_prev and pdu as arguments.
After return from the function the pdu_prev should point to last
PDU from previously used periodic advertising data and pdu should
point to last new periodic advertising data.
The rem_cte_info_from_per_adv_chain function removes CTEInfo from
all but last one PDU. Last PDU must have removed AuxPtr field also.
Remove of CTEInfo and AuxPtr from last PDU is done explicitly in
the cte_info_clear function.
Unfortunately rem_cte_info_from_per_adv_chain had wrong type of
parameters for pdu_prev and pdu. These parameters were pointers
instead od double pointers.
That caused cte_info_clear function to remove CTEInfo and AuxPtr
from first PDU in a chain, which is AUX_SYNC_IND.
Changed parameters pdu_prev and pdu in the rem_cte_info_from_per_adv_-
chain to be double pointers.
Added small corrections in comments.

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.
