4321f86f1e drivers: allow setting BlueNRG public address
The zephyr bluetooth stack expects the controller to know its public
address, if any. At least for BlueNRG, the public address is forgotten with
every reset/power cycle, so there needs to be a way to set it from within
zephyr. This is accomplished using the `Aci_Hal_Write_Config_Data` HCI
command, as described in PM0237.

9cf07bbdb5 bluetooth: Rename rpmsg HCI driver and sample to ipc
The existing driver and sample:

- drivers/bluetooth/hci/rpmsg
- samples/bluetooth/hci_rpmsg

are no longer correctly named, since they now use the IPC subsystem to
send and receive data. The IPC subsystem can use RPMsg as a transport,
but that is one of several selectable backends.

I initially wanted to deprecated both the BT_RPMSG Kconfig option as
well as the zephyr,bt-hci-rpmsg-ipc chosen node in Devicetree. However,
this proved to be undoable in the case of the Kconfig option. This is
because it's a choice option, and those have special behavior. In
particular, the only practical way to deprecate would've been to keep
the old Kconfig option outside the choice (much like it's done in this
commit) but then also add a 'depends on !BT_RPMSG' on each of the
remaining choice symbols *except* on the new BT_HCI_IPC one. This, however,
only works correctly for .conf files. If a board instead sets the
default BT_HCI_BUS_TYPE in the Kconfig.defconfig file then the Kconfig
tree parsing would fail, because it'd try to set it to a value
(BT_RPMSG) that is no longer part of the choice.

322d4c1f98 bluetooth: hci: spi: avoid rxmsg re-use
Don't re-use the `rxmsg` buffer in the `bt_spi_send` function. This
buffer is still used by the RX thread after releasing the SPI semaphore.
The current re-use can result in buffer corruption if the RX thread is
swapped out as a result of the `k_sem_give`.

Moving the semaphore release later can result in deadlocks due to
buffer allocation being performed while holding the semaphore, so
instead just eliminate the re-use entirely.

ranges on that symbol are already defined in terms of software features,

b3f12b430f drivers: bluetooth: hci: spi: add small read delay
Add a small delay between reading the transport header and reading the
HCI data. Failing to do so on a nRF9160<->nRF52832 link was reliably
resulting in the nRF9160 trying to read data before the nRF52832 had
set up the SPI transaction, resulting in the host reading a buffer full
of 0x00 and having to run the entire read result again.

Transceiving a 10 byte packet takes at least 31uS, while 100 byte
packets are around 150uS (duration of `spi_transceive` call). Waiting
1 tick to eliminate the need for most retransmissions is a valid
tradeoff.

607efa8edd Bluetooth: hci: spi: don't block on IRQ line
Don't wait for the IRQ line to be de-asserted in `bt_spi_send`. As this
function can be called by the RX processing thread, the previous
behaviour could cause deadlocks under heavy load:
 * SPI RX thread starts blocking on `bt_buf_get_evt` due to load
 * BT controller generates another event, asserting the IRQ line
 * RX processing thread calls `bt_spi_send` in reponse to event
 * RX processing thread blocks forever on the removed condition

There is no need to attempt to rate-limit how often `bt_spi_send` is
called to allow the RX thread to run. If the bus is so congested that
there is no remaining capacity, prioritising RX over TX is not going to
improve the situation.
