The OpenTitan watchdog driver is a watchdog driver that can be configured
with two stages: a watchdog "bark", which generates an interrupt, and a
watchdog "bite", which resets the system. The two-stage watchdog can be
enabled by setting CONFIG_WDT_MULTISTAGE=y. Otherwise, the driver
functions as a single-stage watchdog.
A callback function may be set for the bark interrupt through the
wdt setup interface, but will only be used if the two-stage watchdog is
enabled. It must be configured for the first watchdog stage.
The driver controls only the watchdog portion of the OpenTitan AON timer.

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.

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.

Added a new watchdog driver which can handle a multiple wdt_dw instances
and can control the pause signal.
The mlt platform has three designware watchdogs, one for each core.
I decided to create a separate intel watchdog driver for the following
reasons:
1. All three devices share the same interrupt number. Each watchdog reports
an interrupt to the core to which it has been assigned. The same interrupt
number cannot be used by multiple devices in the device tree. So, it would
be assigned to only one device. The other dw watchdog devices would use
this assignment, even though it would not be described for them in the dt.
The interrupt handler function in dw watchdog checks the interrupt flag.
If the interrupt was connected to the first watchdog, and the second or
third watchdog signal an interrupt, the interrupt handler of the first
device would ignore it because it would not have set the interrupt flag.
The watchdog device don't knows anything about the existence of the others
devices.
2. The designware watchdog only supports a hardware pause signal. It cannot
be paused programmatically. On the mtl platform, there is a separate group
of control registers for all per-core watchdogs. There are GPIO-like
registers that allows control of a hardware pause signal for subordinate
watchdogs. This separate block is shared by all three watchdogs.
3. The base addresses of the subordinate watchdogs are read from the
aforementioned control registers. As a result, in the device tree we have
only one base address for the intel watchdog, which points to the pause
control registers and containing the base addresses of the subordinate
devices.

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

This adds a basic Intel TCO watchdog driver. The driver doesn't support
windowed timeouts (a non-zero window.min value) or callbacks. The driver
currently assumes TCO version 6, which can be found e.g. on Elkhart Lake
and Raptor Lake platforms. The driver also expects the TCOBA base
address to be specified through DTS, rather than doing runtime lookup
(using e.g. ACPI or PCIe).

When using watchdog which doesn't support callbacks (e.g. STM32 IWDG)
it's very useful to have counter based watchdog with shorter timeout.
This way we can gather useful information before IWDG resets SOC.
In above case it's usually not desired to reset SOC when counter
watchdog is triggerd, because we can lose information about reset cause.
For example, STM32 can determine if the reset was caused by watchdog.
Another use case for counter watchdog without SOC reset is to detect
slow code paths.
