f43e4e0637 Bluetooth: controller: Fix assert on peer unknown rsp
Fixed an assert when peer responded with unknown rsp to
slave feature request when an existing another control
procedure was in progress.

This assert happened with a BT v4.0 peer implementation that
was performing a channel map update and local controller
initiated a slave feature request, receiving an unknown
response.

93ca60b733 Bluetooth: controller: Require nRF52 for privacy
Privacy on nRF51 is not passing the conformance and qualification tests
due to the time it takes to execute the privacy code while in ISR. Until
we come up with a way of optimizing and/or deferring the work, do not
allow privacy on nRF51 targets.

38b148023e Bluetooth: controller: Fix assert on connection establishment
Fixes an assert during connection establishment when the
initiator overflows the initiator window in time while
sending the CONNECT_IND PDU. The actual window is one low
frequency tick less, hence corrected the check that permits
the transmission of CONNECT_IND PDU inside the initiator
window.

Symptom was, stopping of the scanner's ticker succeeds on
connection establishment, but next interval prepare was
already run when continuous scanning was used, breaking the
design, hence there was an assert.

94bab6ca8c Bluetooth: controller: Fix Read Peer RPA Command
There are 2 possible interpretations regarding the address to return in
response to the Read Peer RPA HCI Command:

1) The RPA that the local controller generates to be used in certain
packets it sends
2) The RPA generated and used by the peer device in its packets

We used to return 1) but our interpretation turned out to be incorrect
when reading the HCI test specification, so this commit switches to
returning 2).
