Relax the radio packet pointer assignment deadline assertion
until access address being transmitted. The PDU buffer is
probably only needed just after access address is being
transmitted or received by the radio. This will give some
more breathing room for slow CPUs like in nRF51x SoCs.

There was an issue where terminating the BIG while in the
ISO connected callbacks could lead to continueing the loops
would cause access to cleared memory.
The simple solution to this is to simply prevent
bt_iso_big_terminate from terminating the BIGs while we are
processing the BIG HCI events.

Unlike legacy Zephyr Controller's double headed Tx queue
linked list, the new split Zephyr Controller's new LLCP does
not place a control PDU at the head of the Tx queue causing
control PDUs to be delayed on air.
Pause the data enqueue until pending PDUs are transmitted
across before enqueuing LE Connection Update Ind PDU, and
thereafter resume other PDUs being enqueued again.
There can still be connection timeout if enqueued PDUs are
not being transmitted/acked during repeated retransmissions.

Single timer use needs additional event overhead to start
radio to ensure the software switch implementation executing
in radio completion ISR can correctly set the tIFS switching
after a maximum radio ISR latency.
The latency value shall be the used additional overhead so
that there is no spurious tIFS switch before radio ISR
executes.
The additional event overhead value is not considered in the
event overhead check.
