ddd83c3bc0 Bluetooth: controller: correct conditional compile for central FEX
In the switch statement there are two cases guarded by ifdef's.
These cases are not compiled in for the following Kconfig settings:
BT_PERIPHERAL=n
BT_CTRL_PER_INIT_FEAT_XCHG=n
The following function call then becomes dead code
This is fixed here by adding the proper guards around the whole case
statement

659294bc3f Bluetooth: Controller: Fix AUX_ADV_IND AUX_SYNC_IND radio utilization
Fix AUX_ADV_IND AUX_SYNC_IND radio utilization by having a
configurable offset.

Define an offset between AUX_ADV_IND and AUX_SYNC_IND when
using Advertising Interval for the Extended Advertising and
Periodic Advertising that are same or multiple of each
other, respectively.

Note, to get advertising intervals that are same or
multiple, the Periodic Advertising Interval shall be 10
millisecond more than the Extended Advertising Interval;
this is because the AUX_ADV_IND PDUs are scheduled as
periodic events of Extended Advertising Interval plus 10
milliseconds (Advertising Random Delay) as the periodic
interval.

98161bd1d3 Bluetooth: controller: Enable CIS establishment in same ACL instant
If CIS offset in LL_CIS_IND is less than EVENT_OVERHEAD_START_US, the
controller is not able to establish the CIS in the ACL connection event
specified, but needs to start setup one connection event earlier.

With this commit, if offset is larger than EVENT_OVERHEAD_START_US the
first CIS event can be prepared in due time immediately.

This enables the controller to setup first CIS, even when instant is
equal to the ACL event_counter.
