For systems with a true dynamic 1-Wire nature, the 1-Wire devices
cannot be defined in the DeviceTree (the number of slaves in
the system is not known during the build time).
In other words, there are no pre-defined 1-Wire devices on the bus in
DeviceTree, and thus the slave_count variable is always zero.
That means the skip_rom functionality will always be called even if
there are multiple devices connected to the bus.
This commit allows the user to override this original behavior and avoid
the skip_rom call by ignoring the slave count variable.
Also, this work preserves full backward compatibility.

Add a driver for the Xilinx AXI Timebase WDT logic core. This can be
instantiated on various Xilinx FPGA-based platforms such as the
Digilent Arty, although it is not part of the default image used with
the Zephyr board configuration.
The driver can also optionally implement the HWINFO API to allow
determining whether the last system reset was initiated by the WDT.
Since this is a standalone IP core which could be used a variety of
configurations, this support is optional in case the system/SoC it is
used with already implements this support.

Some miscellaneous fixes to LPC DMA driver regarding status tracking:
- If a DMA channel has not been configured for any transfer,
there will be a bug caused by the virtual channel being -1
and then trying to index -1 into the driver data structs.

- Return -EINVAL from get_status if channel number is invalid
- Update the busy flag in the LPC DMA callback function.

Commit 246393e830
("drivers: spi: spi_nrfx_spim: Remove nrf_frequency_t handling")'
introduced two changes, one of them is removing the function
get_nrf_spim_frequency with a strange justification.
This change breaks support for peripherals written in a common way,
where the maximum frequency is set to the maximum supported
by the peripheral, not the controller, see shields for example.
On the occasion of bringing it back, the original function was
refactored to be easier to read and understand.

API function:
- `pl011_irq_tx_enable` is expected to enable and trigger TX interrupt.
Due to HW limiation, PL011 won't trigger TX interrupt if some data
wasn't filled to TX FIFO at the beginning. So that `isr_cb` must be
called at first time to enable TX irq.
- `pl011_irq_tx_ready` will return true when FIFO can accept more
data. Here we don't need wait TX FIFO to be empty.
- `pl011_irq_tx_complete` will return true when all data have been
sent from the shift register.

To reduce the interrupt latency of MIWU events, the driver prepares a
dedicated callback function item list for each MIWU group in this PR. We
needn't check the MIWU table and group of the event in ISR. And the
maximum item number of each list is also limited to 8. After applying
this PR, the interrupt latency reduces to ~10us consistently.

Glitches were observed if a GPIO pin was configured by
ROM to a non-default state and then Zephyr PINCTRL
reconfigured the pin. The fix involves using the correct
PINCTRL YAML output enable and state flags. Reading the
current spin state and reflecting into new pin configuration
if the pin is output and the drive low/high properties are
not present. We also take advantage of GPIO hardware reflecing
the alternate output value in the parallel output bit before
enabling parallel output mode. Interpret boolean flags with
both enable and disable as do not touch if neither flag is
present. We give precedence to enable over disable if both
flags mistakenly appear. Note, PINCTRL always clears the
GPIO control input pad disable bit.

A glitch was observed if a GPIO PIN was configured to a
non-default state by ROM and then Zephyr programs the pin
for the same configuration. Root cause is GPIO hardware
implementing two output bits for each pin. The alternate
output bit is in the pin control register and is r/w by
default. The other bit exists in the GPIO parallel ouput
register and is read-only by default. The hardware actually
reflects the pin's output value into both bits. The fix is
to configure the pin with alternate output bit read-write
and the last step is to disable alternate output which
enabled read-write of the parallel bit. GPIO API's can
then use the GPIO parallel out registers. Add logic to
return an error from the GPIO interrupt configure API if
a pin is not configured as an input. Hardware only performs
interrupt detection if the input pad is enabled.
Hardware supports a pin being configured for both input
and output. Applications should add the GPIO_INPUT flag
to all pin configuration requiring interrupt detection.
The interpretation of input and output flags for the
get configuration API appears to be only one of the
flags can be set. Please refer to the GPIO driver tests.
Updated GPIO interrupt configure to clear the input pad
disable bit due to interrupt detection HW is connected
only to input side of pin.

rx_thread() is started by eth_initialize(), while dev_data->iface is
populated by eth_iface_init() (called by net_init()).
Usually eth_iface_init() has completed by the time rx_thread() hits its
idle timeout and accesses dev_data->iface, but in case of a time-intensive
SYS_INIT item between eth_initialize() and net_init(), this is not
necessarily the case, causing a NULL dereference. This can be forced by
putting a k_sleep(K_SECONDS(5)) at the top of eth_iface_init().
Start rx_thread() in eth_iface_init() instead (which runs after
eth_initialize() due to init priorities) to make sure everything is
initialized properly.
