Bluetooth: controller: Add IQ report mem pool management Add functions that will allow to mangage IQ reports memory pool e.g. allocate or relase new IQ report nodes. Signed-off-by: Piotr Pryga <piotr.pryga@nordicsemi.no>

Bluetooth: controller: ULL: Add init of DF sync configuration lll_sync object is used to store information for LLL to enable or disable CTE sampling. The commit adds initialization of lll_df_sync member of lll_sync. Signed-off-by: Piotr Pryga <piotr.pryga@nordicsemi.no>

Bluetooth: controller: Dropp IQ sampl report if CTE disabled after evt end Disable of CTE sampling for periodic advertising sync PDUs may be interrupted by radio event. In such situation, TX thread will be handled before RX thread delivers IQ samples report to host. In this case RX thread would deliver IQ samples report after CTE sampling was disabled. To avoid such situation RX thread has to check if: - CTE sampling is not disabled, - CTE sampling was not requested to be disabled after start of radio event. CTE sampling configuration is double buffered. Updated configuration is swapped at the beginning of radio event. If CTE sampling is diabled or requested to disable (next radio event didn't start), the IQ samples report should be dropped by RX thread and should not be delivered to host.

/* Returns information if CTE sampling for periodic sync is requested to disable. */
Bluetooth: Controller: Add CTE recv and sample in connected mode In connected mode when Receiving Constant Tone Extensions feature is enabled, controller shall be able to receive CTE in any data channel packet. The commit adds required changes to allow receive of CTE for all data channel packets in peripheral role. Signed-off-by: Piotr Pryga <piotr.pryga@nordicsemi.no>
