In order to achieve proper sharing of configuration options, everything
that is common to both the Host and the Controller should now be placed
in the top-level Kconfig file, and Controller-only options are in the
controller/ Kconfig one.

Introduce alternative TRX switching using dedicated timers
and peripheral interconnect. This will enable the
possibility to independently configure the Tx and Rx
settings between the tIFS.
Note, this will also provide the opportunity to design a
soft realtime Radio ISR.

The TX and RX pool needs to be split otherwise the TX code path may
consume all buffers causing the RX thread to deadlock which will
possible deadlock the TX thread as well in case it needs more credits.

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.

There're (at least) 2 UART TX interrupt causes: "tx fifo has more
room" and "transmission of tx fifo complete". Zephyr API has only
one function to enable TX interrupts, uart_irq_tx_enable(), so it's
fair to assume it enables interrupt for both conditions. But then
immediately after enabling TX IRQ, it will be fired with "tx fifo
has more room" cause. If ISR doesn't do anything to fill FIFO, on
some architectures, immediately after return from ISR, it will be
fired again (with no instruction progress in the main application
thread). That's exactly the situation with this test, and on ARM,
it leads to inifnite IRQ loop.
So, instead move call to uart_fifo_fill() inside ISR, and be sure
to disable TX IRQ after we transmitted enough characters.

The segment allocation function can't fail (it eventually waits with
K_FOREVER for a buffer to become available), so there's no point in
checking its return value for NULL. Also, the connection state check
is because of this particular waiting and not the semaphore waiting
(which is done with K_NO_WAIT).
