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.

Fix a race condition that caused the Controller to deadlock
waiting for a semaphore that be given when LLL events have
been disabled.
ULL reference count is checked in thread context to decide
if LLL events are pending, but the reference count can be
decremented by the ULL execution context which prevents the
set `disabled_cb` function not being called due to no
pending event to produce the done events.
Fixed by re-checking if reference count is zero and avoid
waiting to take the semaphore.

The new JIT scheduler does not have slot reservation, which means that
the ticker extension feature for automatically re-scheduling a colliding
non-anchored event, e.g. ADV, cannot be used.
This implementaion reacts to ADV envent done with result ABORTED or
TOO_LATE, and in those cases attempts to re-schedule the ADV event again
within the 10 ms pertubation window.
As the original scheduling, the re-scheduling is randomized, so there
is no absolute predictability as to how many attempts will be made. The
advertiser will attempt with randomly delayed re-schdules until the
window is exhausted.
If re-scheduling is unsuccessful, the weight of the ADV event is
increased, improving it's chances of success in the next event.
