Fix k_sem_give() from being called from Zero Latency IRQs
when the Controller is configured with BT_CTLR_ZLI=y.
Kernel features shall not be used from Zero Latency IRQs as
these IRQs cannot be locked by the kernel to maintain
context safety of the kernel objects.
Relates to commit 92e017fd70 ("Bluetooth: controller:
split: Support Zero Latency IRQs") and
commit c842eef3ae ("Bluetooth: controller: Add semaphore
to indicate free AD data buffers").

sw_switch implementation uses two parallel groups of
PPIs connecting radio and timer tasks and events.
The groups are used interchaneably, one is set for
following radio TX/RX event while the other is in use
(enabled).
The group should be disabled by timer compare event that
starts Radio to TX/RX a PDU. The timer is responsible for
maintenance of TIFS/TMAFS. The disabled group collects
all PPIs required to maintain the TIFS/TMASF. After
the time is reached Radio is started and the group is
disabled. It will be enabled again by software radio
swich during next call.
If the group is not disabled then it will work in parallel
to other one. That causes issues in correct maintenance of
instant when radio shoudl be started for next TX/RX event
e.g. radio may be enabled to early.
In case the PHY CODED was enabled and periodic advertising
included chained PDUs, that are transmitted back-to-back,
there was missing group delay disable. The missing case was
sw_switch function called with dir_curr and dir_next set

- Prevent double callback with ADV re-scheduling
For configurations using CONFIG_BT_CTLR_JIT_SCHEDULING, when last
ADV before initiating connection is re-scheduled with a small delay,
the disabled_cb would be called a second time. This would unexpectedly
invoke a second conn setup with illegal parameters.
To avoid this JIT scheduler phenomenon, clear the ADV disabled_cb
when invoked.
- Add priority to LLL header. This allows the conn priority to be
associated with the object. Used in vendor LLL implementation.

Periodic advertising sync may be created with CTE type filtering
enabled. When received AUX_SYNC_IND, there are HCI_LE_Periodic_-
Advertising_Sync_Established and HCI_LE_Periodic_Advertising_Report
events generated. In case received AUX_SYNC_IND has wrong CTE type,
HCI_LE_Periodic_Advertising_Sync_Established event is generated.
There may not be HCI_LE_Periodic_Advertising_Report event generated.

CONFIG_BT_CTLR_DF_CTE_RX is enabled by default if CONFIG_BT_CLTR_DF
is enabled and there is support for DF in given SOC.
If CONFIG_BT_CTLR_DF_SCAN_CTE_RX is disabled then the CONFIG_BT_CTLR-
_PER_SCAN_CTE_NUM_MAX is not available.
It causes build errors if that particular configuration is used by
an application. It was a case for example in split builds of direction
finding connectionless TX sample application were periodic advertising
was enabled but perddioc advertising sync was disabled.

Nordic Semiconductor Radio peripheral provides IQ samples as
12 bits signed integer with sign extended to 16 bits.
Where out of range IQ samples (saturated) have value -32768.
Due to conversion of IQ samples to 8 bit signed integer, required by
BT 5.3 Core Vol 4, Part E sections 7.7.65.21 and 7.7.65.22 the
saturation information was lost.
The PR fixes that issue by use of value -128 to mark saturated
IQ samples. Note that BT 5.3 Core does not give any particular
value of IQ sample a special meaning.
This is a vendor specific solution and does not affect other
implementations of lower link layer.
