571f26cf1a Bluetooth: Rename BLE to Bluetooth (LE) where applicable
The BLE acronym is not an official description of Bluetooth
LE, and the Bluetooth SIG only ever refers to it as Bluetooth
Low Energy or Bluetooth LE, so Zephyr should as well.

This commit does not change any board or vendor specific
documentation, and the term BLE may still be used in those.
It will be up to the vendors to update it if they want,
since many of them are using the term BLE in their

Fix single timer s/w switch when using DPPI on nRF53/54L

The issue is discovered as failing ISO Receiver sample with

configured to use the DPPI 3 (instead of 4).

Upstream samples do not use single timer for s/w switch, the
issue is discovered when adding support for nRF54L which has
to use single timer due to the radio only having a single

37bf99eee7 Bluetooth: Controller: Fix radio_tmr_start_us for single timer use
This commit addresses two bugs in use of single timer s/w
switch implementation, incorrect aux_offset in subsequent
ADV_EXT_IND and ISO receiver failing to receive second or
greater BIS subevents.

Fix radio_tmr_start_now implementation to consider the
initial latency in starting the event timer in single timer
use mode. This fixes the incorrect aux_offset in ADV_EXT_IND
PDUs.

Fix radio_tmr_start_us implementation for single timer use,
as the timer is reset on every radio end, and hence the
requested start_us has to be adjusted for the accumulated
last_end_pdu_us value. This fixes the BIS subevent
receptions.

Also, fix the maximum radio ISR latency value used in
radio_tmr_start_us to consider the maximum Rx chain delay
and maximum radio ramp up delays. 80 us + ~30 us + ~40 us
should be able to meet the 150 us tIFS duration.
