Direction finding functionality does antenna switching during CTE
reception in AoA mode and CTE transmission in AoD mode. Antennas are
switched according to user provided antenna switch pattern. If a CTE
length is enough to exhaust all antenna ids in a switch pattern then
Radio should loopback to reference antenna and continue from switching
from it.
Current implementation loops back to wrong antenna due to wrong index
used in GUARD_REF_ANTENNA_PATTERN_IDX. It was set to one instead of
zero. Zero is the index of reference antenna in Host provided antenna
switching pattern array.

Refactor PDU chaining implementation to add aux offset in
the aux pointer field in the parent PDU when duplicating
chain PDUs.
By adding the aux offsets in the ULL execution context the
LLL prepare execution in Extended and Periodic Advertising
does not need to have a O(n) while loop in LLL execution
context.
This will reduce CPU use in the highest priority ISR
compared to current implementation where chain PDUs where
duplicated in ULL execution context and aux offset populated
in LLL execution context.

When directed advertising and continuous scanning are
simultaneously active, and a connection request is received
by the directed advertising state then the connection was
not established due to the done event not being generated.
Done event from the directed advertising state was not
generated because the prepare pipeline only had resume
event which does not get scheduled when there is prepare
event of the continuous scan state.
The fix is to explicitly abort all pending prepare and
resume event in the pipeline for the directed advertising
state when connection request is received.

Nordic Radio Direction Finding Extension provides 12 bits wide IQ
samples. The Bluetooth Core Specification 5.3 Vol 4, Part E sections
7.7.65.21 and 7.7.65.22 limits IQ samples to be 8 bits wide.
There are other way to convert 12 bits IQ samples into Bluetooth Core
specification compliant 8 bits IQ samples than ordinary 4 bits right
shift. If one is sure that samples will never go over 10 bits or 8
bits then, it is allowed to use 2 bits right shift or even 8 least
significant bits of 12 bits IQ samples.
The commit introduces a possibility to choose which approach is used
for IQ samples conversion in HCI layer while Host IQ report events
are created.

The initialisation of DLE parameters for the peripheral
was done before the intialisation of the PHY settings.
Since the DLE parameters depend on PHY settings this
can result in incorrect parameters for tx/rx time and
octets
One scenario is where a previous connection set the PHY to
2M or CODED, then when a new connection is established
it uses the same memory-locations for connection settings as the
previous connection, and the (uninitialised) PHY settings will be
set to 2M or CODED, and thus the DLE parameters will be wrong
This PR moves the initialisation of DLE parameters after
that of PHY settings

PHY update control procedure has to send a notification towards
Host when the PHY is actually changed, when the instant happens.
Control procedures are handled in a prepare phase of a connection
event, hence notifications are send towards host to early.
The fix for that is to postpone send of a notification.
New state has been introduced to remote requested PHY update
control procedure: RP_PU_STATE_WAIT_INSTANT_ON_AIR.
Also new event has been introduced: RP_PU_EVT_NTF, that is used
to inform the PHY update state machine that notification may
be send.
There are two places where the notification events may be generated
ull_conn_rx, just before first received PDU is send towards Host
or ull_conn_done, in case there were no PDU received.

Mayfly by design uses a memq for storage of its jobs. The memq
requires head and tail to track the content. It is considered
empty is head equals tail.
When memq instance is initialized then there is a new link
instance stored in head and tail, nevertheless the memq is
still empty.
When new job is enqueued to a memq, the inilial link is used
to store the job. New link, provided by enqueue call, is stored
in the tail for future enqueue.
When enqueued job was served and is dequeued, the link it was
assigned to is returned and stored in the job object.
That link will be used in future for call to enqueue.
Now lets consider a situation when we are just after initalization.
Some default initial link is in empty memq. We enqueue and dequeue
a job. After dequeue, the job object stores the initial link object.
The one that was put into the memq during initialization.
Next Bluetooth stack is disabled and enabled again.
The job is enqueued again, but it still stores the initial link
address. After enqueue the memq head points to initial link object,
that stores new job. Tail points to link deliveded by enqueue call,
that is also the initial link object. The memq is considered to be
empty, nevertheless there was a successful enqueue operation.
The issue is casued by lack of re-initialization of a job object
on init. In most cases these objects are static members of some
functions, hence there is no re-initialization after bt_disable
and bt_enable calls.
The problem is fixed by re-initialization of mayfly only once
on bt_enable() call. Then it doesn't matter what links are stored
in dequeued objects and there is no need to re-initialized mayfly
job objects.
