87fe440f01 Bluetooth: controller: Prepare to introduce LL split architecture
Preparation to introduce the Upper Link Layer (ULL) and
Lower Link Layer (LLL) split architecture.

- Move SoC dependent HAL to vendor specific folder.
- Preparation to split data structures into ULL and LLL
  types.
- Added more role and state conditional compilations.
- Added some work-in-progress implementation of advertising
  extensions, will be used as inspiration in the new split
  architecture work.

362a6b34c7 Bluetooth: controller: Fix to use max. tx power in DTM test mode
According to the Bluetooth Specification v5.0, Direct Test
Mode shall use maximum Tx power.

Fixed by adding nRF5x Radio HAL interfaces to get supported
maximum Tx power for SoC selected, and DTM testing sets the
Radio peripheral to use maximum Tx power.

Fixes #7243

74cd8d852e Bluetooth: controller: Use single PPI channel for AA capture
Earlier design captured AA twice in the first Rx in a slave
connection event and retained one of the capture until end
of event to calculate drift.

Design updated to use single capture of AA and save the
first AA capture in a slave connection event in RAM instead.

This frees up a PPI channel in the controller design.

c3adc7b0c7 Bluetooth: controller: PHY Update Procedure
Added support for Bluetooth v5.0 PHY Update Procedure in the
Controller.

Asymmetric PHY connections do not work for now due to the
Radio mode not being setup in time in the ISR during tIFS
period and the Radio already ramping up in the cached
previous Radio mode to meet tIFS deadline.

Subsequent commits will add this feature, by either double
buffering the mode in software or using fast radio ramp up
which gives enough time in the ISR to change the mode.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

d5d473b0f8 Bluetooth: Controller: replace work with mayfly
This commit introduces a very light-weight and lock-less
scheduling of the Controller's deferred function calls
called the Mayfly.

Earlier work implementation used in the Controller had an
O(n) to schedule a function in a linked list that used IRQ
lock during modification of the linked list in the
Controller's ISR executions.

Mayfly is a compile time configurable matrix of queues
where an execution context-safe queue exists between two
execution context, one being the caller and the second
being the callee. Callee(s) are run in a software interrupt
but can also be run in an OS thread.

There are minor clean ups too in this commit related to
folder structure.

6de7a808af Bluetooth: Controller: ctrl pdu processing based on available CPU time
On CPUs like nRF51 which run at 16MHz, certain BLE control
procedure PDU processing take more CPU time than permitted
inside tIFS (150us). Current implementation of Data Length
Update procedure does not span over multiple connection
interval (unlike Encryption Setup, which is another control
procedure processing that would consume more CPU time)
hence taking more CPU time inside tIFS on nRF51.

During the radio ISR, the active clock and packet timer are
active and it is used to profile the CPU time taken which
is used to decide on whether there is sufficient time in
the current radio event to process the control packet.

This commit also fixes a potential bug that would cause
disconnection due to MIC failure on encrypted connections
that performed Data Length Update. Controller used to NACK
the request/response PDU if it was not in a state to resize
the receive buffers but did not reset the CCM counter. This
is now fixed by the change done to NACK control PDU based
on available CPU time in radio ISR.
