07278fc98f Bluetooth: controller: Guard against race in conn. establishment
In the time between a NODE_RX_TYPE_CONNECTION node is sent from LLL and
demuxed in ULL, an ADV role disable may be executed.
This makes the LLL data referenced in the node NULL/invald, and
ull_conn_setup would operate on invalid data.

This commit introduces a check in ADV disable to disallow the operation
(including conn invalidation), if a connection has been initiated.

To prevent pipeline-queued prepares from advertising after disable has
been initiated, set 'cancelled' flag for immediate signalling to LLL.

5ce5dc055e Bluetooth: controller: Avoid race between ULL and LLL when initiating conn
Use an "initiated" flag in the lll_conn struct to guard the processing
of PDUs related to connection initiation (CONNECT_IND,
AUX_CONNECT_RSP). This avoids races between ULL and LLL when creating
a connection.

abd1d047dd Bluetooth: controller: enable dynamic TXP over LL_SPLIT arch (#17731)
This commit targets solving issue #17731 over the LL_SW_SPLIT
arch of the BLE stack in Zephyr. This functionality is exposed
to the user as HCI Zephyr Command extensions

- BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL
- BT_HCI_OP_VS_READ_TX_POWER_LEVEL

which enable Tx power read/write operations within BLE radio events
on a per role/connection basis.

The functionality is enabled upon the Kconfig advanced configuration
triggered by

- BT_CTLR_TX_PWR_DYNAMIC_CONTROL

depending on the enablement of Zephyr HCI vendor-specific command
extensions.

Necessary low-level radio HAL functionality and power definitions
are also supplied to address the high-level functionality of
controlling the Tx power.

1475402d41 Bluetooth: controller: Introduce ULL LLL architecture
This is a squash merge of commits introducing the new split
Upper Link Layer and Lower Link Layer architecture of the
Bluetooth Low Energy controller.

This introduces a new, improved Link Layer based on the
concept of split responsibilities; The Upper Link Layer
(ULL) is in charge of control procedures, inter-event
scheduling and overall role management. The code for the
ULL is shared among all hardware implementations. The
Lower Link Layer (LLL) is responsible for the intra-event
scheduling and vendor specific radio hardware access.

The communication between ULL and LLL is achieved through
a set of FIFOs that contain both control and data packets.
