When checking the absolute value of cycles set to the comparator
use the MAX_CYCLES instead of MAX_TICKS.
The commit changes function names and comments to make it clear
where ticks (system ticks) and where RTC cycles are used.

It is annoying to read just a single word at a time. Update this
command to print any amount of data. This uses byte format at present.
We could perhaps support something like:
flash read.8
flash read.16
flash read.32
to chose the size.
Example output (with line breaks to keep within git-style limit):
$ flash read FLASH_CTRL 0 20
00000000: 20 25 00 20 1d 26 00 08 69 68 00 08 45 26 00 08

K_FOREVER/INT_MAX number of ticks needs delay cycles value of
maximum order and exceeds 'int32' range.
The typecast to 'int32' results in wrongly evaluating the value
as less than 'MIN_DELAY' and chooses 'MIN_DELAY' over the actual
delay cycles.
Cap the 'MAX_TICKS' to INT32_MAX.

Make sure to retry at least once after the timeout elapses. Sample the
current time before starting the i2c transaction, and only give up if
the polling occurred after the timeout.
The timeout exists to allow the eeprom time to complete a write, during
which time it will nack transactions (at24) or the status register will
report busy (at25). If a transaction fails legitimately, but the 1ms
sleep overshoots the timeout expiration, we will not try again, which
fails to give the part the full grace period before declaring failure.
This is likely to happen in the last 1ms interval but also possible if
the eeprom thread is preempted. It is possible to only try once and give
up if the sleep lasts longer than the timeout, which fails to give the
part an adequate period to complete the write.
Waiting until the current time is after (not equal to) the timeout is
also important because we don't want to round up partial milliseconds if
the start time was sampled near the end of a millisecond boundary. The
timeouts of eeproms can be ~5ms.

A call to atomic_set_bit_to() was used for clearing bits in an atomic_t
variable that stores information about allocated GPIOTE channels.
This caused an issue to be reported by Coverity, as the function treats
its first parameter as an array and it was provided with a pointer to
a singleton.
This commit replaces that call with atomic_and(), to prevent the issue
from being reported and for consistency with the way bits are set for
allocated GPIOTE channels (what is done with a call to atomic_or()).

The STOPTX task cannot be triggered directly in the function that
disables TX interrupt because this task stops the UART transmitter
immediately, even if it is in the middle of shifting out a byte.
Instead, this task needs to be triggered in the interrupt handler,
when the end of transmission is signaled.

To keep the bus fully loaded, the SAM0 has a fast path that recognises

The SAM0 has a data register and a shift register. Data that is
written to the data register is transferred to the shift register by
the peripheral.
On the SAMD51, the CPU is fast enough that the first data write hasn't
been transferred to the shift register by the time the next data write
occurs, causing the second write to be dropped, causing the receiver
to wait forever.
Fix by spinning until the data register is empty.

Fix host RX thread being deadlocked. The deadlock occurs because the
RX thread is stuck waiting in conn_tx_alloc with K_FOREVER but if the
connection is disconnected only the RX thread can unblock it in the
handling of the disconnect event.
This commit fixes this deadlock by splitting the processing of the
disconnected event into two parts.
The part needed to unblock the RX is to release resources held by
unack'ed TX packets and mark the connection state as not connected
anymore.
The RX thread waiting for free_tx fifo and the TX thread waiting for
the bt_dev.le.pkts semaphore will both check the connected state after
having acquired them and will abort if disconnected.
The rest of the processing will be handled at normal RX thread
priority like normal.
Move the bt_recv_prio handling to the Bluetooth host when the host
has defined its own RX thread (CONFIG_BT_RECV_IS_RX_THREAD=n).
If the HCI driver has the RX thread (CONFIG_BT_RECV_IS_RX_THREAD=y),
then the responsibility to call bt_recv and bt_recv_prio correctly
falls to the HCI driver.
The helper function bt_hci_evt_is_prio() is replaced with
bt_hci_evt_get_flags() so that the HCI driver can do this correctly.
This decision to replace was made so that existing HCI drivers
maintained out-of-tree will fail at compile time with the new system.

ringbuf claim API returns pointer to contiguous area. In cases when data
in ringbuf wraps the end of internal buffer, then single call to claim
data is not enough to get all data - there is remaining part on the
beginning of internal buffer. Those remaining bytes will need to wait
for next ISR handler to trigger workqueue. Theoretically this means that
data on the beginning of ringbuf can wait there forever, or simply to
the next timeout in PPP stack when data traffic continues.
Consume data from ringbuf in a loop, stopping only when claiming results
in empty buffer. This will make sure that there is no stale data in the
ringbuf.

Remove K_FOREVER wait on completion_sync.
In some situations (a short on I2C SDA line for example), this
semaphore will never be released and therefore we should not wait
it forever.
Instead we wait for a maximum of 100msec and return an error if we
weren't able to retrieve the semaphore.
In such situation, the program is not stuck anymore, but the I2C
driver must be uninit then init again to work again.

Add support for the SX126x series of LoRa radios using the
LoRaMAC-Node HAL.
This driver currently makes the following assumptions:
* DIO1 is used as an interrupt line.
* There is an RF switch selecting between the TX and RX ports and
that switch is controlled by DIO2.
* There is either no TCXO or the TCXO is controlled by DIO3.
Specifically, the limitations above mean that modules that use GPIOs
to control the RF switch are currently not supported. Support for such
modules would need changes to the LoRaMAC-Node code.
