Andrei Stoica 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.

Carles Cufi 058724f329 Bluetooth: controller: Optimize calls to hci_get_class()
Cache the result of calling hci_get_class() to avoid repeatedly invoking
it on the same data. In order to cache it we take advantage of the fact
that both radio_pdu_node_rx_hdr and node_rx_hdr are not packed
structures and they currently have a spare padding byte (between type
and handle).

Wolfgang Puffitsch 34b95feb54 Bluetooth: controller: split: Call LLL reset functions from ll_reset
Call LLL reset functions when calling ll_reset to avoid carrying LLL
state across HCI resets. Respective functions already exist in LLL but
had not been called from anywhere.

Morten Priess 70cbf342ff bluetooth: controller: RX PDU meta data support in LLL
Added support for vendor specific meta data in LLL node_rx_hdr. This
enables vendors to add "footer" data to the RX PDU, for supporting
specialized BLE features.

Vinayak Kariappa Chettimada 8de64fcb81 Bluetooth: controller: split: Fix shell app regression
Fix shell app regression due to stale tmp role implementation
not fully being removed in commit 4c77bf6194 ("Bluetooth:
controller: Remove redundant tmp role implementation").

The regression caused ticker indexes outside of allocations to
be accessed causing application faults and memory corruptions.

Joakim Andersson 34758e8349 Bluetooth: controller: Fix rx_ftr and extra overlapping memory
The the footer structure and extra bytes (rssi, resolving index etc.)
were overlapping in memory, rx_ftr was moved into the header, but the
extra and footer are still being read from the same place, extra was
written to the end. So this avoided memory corruption, but reading extra
reads wrong information.

Code refactored to allow calling of a proprietary rx demux function.
This will enable implementation of proprietary protocols and

Asger Munk Nielsen 58e9ac6811 bluetooth: Controller: Refactor node_rx footer to avoid ptr arithmetic
The old footer was appended after PDU using pointer arithmetic. Now
the footer fields have been moved to the header struct, the
footer fields are now statically located in the data structure,
this is type safe and fields can be referred to by their actual
names rather than indirectly through reference to other members,
thus avoiding pointer arithmetic. Secondly, this change will pave
the way for adding other meta data in the future.

Vinayak Kariappa Chettimada 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.

- Move SoC dependent HAL to vendor specific folder.
- Preparation to split data structures into ULL and LLL
