7e892f8c6f Bluetooth: controller: Remove SC-jitter from ISO pause/resume setup
Because timing of the pause/resume for peripheral/sync is based on
central/broadcaster active clock, the sleep-clock jitter shall not be
added.

417a9e81ec Bluetooth: Controller: Add device tree dependency to selection
This commit makes the device tree configuration decide
which link layer is compiled in. We do this to avoid
hard-to-understand linker errors referencing device tree nodes.

The following configuration creates a difficult to parse
linker error:
* BT_LL_CHOICE contains multiple entries, BT_LL_SW_SPLIT
  is selected.
* Each BT_LL_CHOICE has its own unique device tree node with its
  own "compatible".
* Only one of the link layer device tree nodes has status "okay",
  but not the one corresponding to BT_LL_SW_SPLIT.

The linker error indicates that code using the HCI driver fails
to link with the controller. This because the HCI driver device
tree node references the link layer selected in devicetree which
is not compiled in.

By adding a dependendency to the device tree node, this can no longer
happen. Instead, if BT_LL_SW_SPLIT is now selected in a configuration
file, a Kconfig warning will be issued:

```
warning: The choice symbol BT_LL_SW_SPLIT
(defined at subsys/bluetooth/controller/Kconfig:129) was
selected (set =y), but BT_LL_SOFTDEVICE (defined at
/home/ruge/ncs/nrf/subsys/bluetooth/controller/Kconfig:11)
ended up as the choice selection.
```

This should be easier to understand than:

```
...(hci_core.c.obj):(.data.bt_dev+0x16c):
undefined reference to `__device_dts_ord_132'
```

After this commit we should consider getting rid of link layer
selection from Kconfig completely as the link layer is in practice
selected through device tree.

Unit tests have been updated to satisfy the dts dependency.

For code clarity, this commit adjusts the use of `return` statements

  `foo();`
  `return;`

9fa18600ee Bluetooth: Controller: Fix hang due to loop in node_rx list
Fix Controller hang due to infinite looping caused by
duplicate node_rx enqueued in auxiliary context.

When LLL scheduling is not applied due to invalid aux offset
then ULL scheduling too would skip setting up the reception
after similarly checking the validity of aux offset required
to schedule the reception of auxiliary PDU. This check in
ULL was after the received node_rx being enqueued into the
auxiliary context causing a loop in the list of node_rx.

Dequeue of a list with a loop of node_rx caused an infinite
loop execution in the Controller.

Regression introduced in commit 3590bd648f ("Bluetooth:

transmission, but in case of Radio ISR latency if rx packet
pointer is not setup then Radio DMA will use previously

DMA will overrun this buffer and cause memory corruption.
Any detection of ISR latency will not happen if the ISR
function pointer in RAM is corrupted by this overrun.
Increasing ISR latencies in OS and CPU usage in the
ULL_HIGH priority if it is same as LLL priority in
Controller implementation then it is making it tight to
execute Controller code in the tIFS between Tx-Rx PDU's
