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.

fc6d8d1bc4 Bluetooth: controller: Scan Request Notifications
Implement the framework for LE Scan Request Received Event.
The feature is available under the Controller's advanced
features and will be selected implcitly when Bluetooth v5.0
LE Advertising Extensions feature is implemented.

7ebe7da736 Bluetooth: controller: Controller to Host flow control
The Bluetooth Specification allows for optional Controller to Host flow
control based on the same credit-based mechanism as the Host to
Controller one. This is particularly useful in 2-chip solutions where
the Host and the Controller are connected via a physical link (UART, SPI
or similar) where the Host is sometimes required to ask the Controller
to throttle its data traffic while still making sure that relevant
events get through the line.

This implementation is based on a simple queue of pending events and
data that is populated whenever the Controller detects that the Host is
out of buffers and then emptied whenever the Host notifies the
Controller that is ready to receive data again. Events relevant to the
connections are also queued to preserve the order of arrival.

At this point the Controller ignores the connection handle sent by the
Host and treats all connections equally, and it also queues events even
for connections that have no data pending in the queue. Both this items
can be improved if necessity arises.

Note that Number of Completed Packets will still flow freely from the
Controller to the Host regardless of the pending ACL data packets, which
might lead to inconsistencies in the sequential order of certain
operations that include bi-directional data transfer.

a6e157b61a Bluetooth: Controller: Fix alignment issues from new integer types
The switch from C99 integer types to u16_t, etc. caused misalignment
in structs and function definitions with multi-line parameter lists.

d0eb235510 Bluetooth: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

11a32bf46d Bluetooth: controller: Support BT 5.0 feature set bit fields
Added support in the Controller for increased feature set
bit fields in Bluetooth 5.0. Cached feature set in the
connection context is increased to a uint32_t value to
accommodate 17 feature bits.

priorities of the Radio, Ticker's Worker and JOB IRQs.

This will provide an opportunity to have peripheral IRQ's
of higher level than Bluetooth Controller.
