Use connection interval units of 1250 us for periodic
scheduling of Extended Advertising auxiliary PDU events so
that auxiliary events can be periodically grouped alongwith
the Periodic Advertising Events. This will permit
mitigating overlaps amongst them.

Fix missing ISO Data packet received by Synchronized
Receiver due to incorrect check on sink handle that did
not permit handle value of 0.
Fixed function to get ISO stream context to check for
valid ISO sync context, i.e. not being terminated.
Regression introduced in commit 7c89f1fe9f ("Bluetooth:
controller: Support for separate ISO RX data path").

As EVENT_OVERHEAD_START_US offset is used in ticks unit in
LLL, ULL scheduling using ticker should also use ticks unit
for EVENT_OVERHEAD_START_US when reducing the first ISO
Broadcast and Synchronized Receiver event preparation.
Relates to commit 858dc7fab4 ("Bluetooth: controller: Fix
EVENT_OVERHEAD_START_US jitter").

ULL reference count is checked in ULL_LOW context to decide
if LLL events are pending, but the reference count can be
decremented by the ULL HIGH execution context which can
prevent the set `disabled_cb` function not being called due
to no pending event to produce the done events.
Fixed by checking the reference count in the ULL HIGH
execution context using a mayfly to schedule the check.

The ticker `ticks_drift` is propagated via the ticker
elapsed callback, in order to provide necessary information
to correctly calculate total elapsed durations by states and

Avoid using sizeof to access ULL and LLL struct members.
Based on the alignment requirements of structures, due to
padding between structure members, use of sizeof of previous
struct member to access next struct member is incorrect.
Continue to use explicitly stored parent pointer to access
ULL context. Combine event header and ULL header so that
the parent pointer point directly to the combined ULL
struct.
