watchdog: iTCO: Drop vendor support

iTCO vendor support was introduced in 2006 to support SuperMicro boards
with Pentium 3 CPUs. It was extended in 2009 to support motherbords
with broken BIOS (specifically Intel DG33TL). The code is long since
obsolete, so let's drop support for it.

watchdog: renesas_wwdt: add driver

This driver adds support for the Renesas Window Watchdog Timer (WWDT).
Because it can only be setup once after boot and we cannot know if this
already happened in early boot stages, it is mandated that the firmware
configures the watchdog. Linux then adapts according to the given
setup. Note that this watchdog only reports an overflow to the Error
Control Module (ECM) and does not reset the SoC on its own.

watchdog: Add driver for Intel OC WDT

Add a driver for the Intel Over-Clocking Watchdog found in Intel
Platform Controller (PCH) chipsets. This watchdog is controlled
via a simple single-register interface and would otherwise be
standard except for the presence of a LOCK bit that can only be
set once per power cycle, needing extra handling around it.

watchdog: Add the Watchdog Timer for the NXP S32 platform

The S32 platform has several Watchdog Timer available and tied with a
CPU. The SWT0 is the only one which directly asserts the reset line,
other SWT require an external setup to configure the reset behavior
which is not part of this change.

As a side note, in the NXP documentation, the s32g2 and s32g3
reference manuals refer the watchdog as the 'Software Timer Watchdog'
where the name can be misleading as it is actually a hardware
watchdog.

The maximum watchdog timeout value depends on the clock feeding the
SWT counter which is 32bits wide. On the s32g274-rb2, the clock has a
rate of 51MHz which result on 83 seconds maximum timeout.

The timeout can be specified via the device tree with the usual
existing bindings 'timeout-sec' or via the module param timeout.

The watchdog can be loaded with the 'nowayout' option, preventing the
watchdog to be stopped.

The watchdog can be started at boot time with the 'early-enable'
option, thus letting the watchdog framework to service the watchdog
counter.

The watchdog support the magic character to stop when the userspace
releases the device.

watchdog: Delete the cpu5wdt driver

This driver has a number of issues (accesses arbitrary I/O ports
without identifying the hardware, doesn't document what hardware it
supports, suspiciously inconsistent locking model, doesn't implement
WDIOC_SETTIMEOUT, potential integer overflow...)

The driver was added in 2003 and there's no evidence that it has any
recent user, all changes seem to be tree-wide, subsystem-wide, or the
result of static code analysis. So I believe we should simply drop
this legacy piece of code.

watchdog/pseries-wdt: initial support for H_WATCHDOG-based watchdog timers

PAPR v2.12 defines a new hypercall, H_WATCHDOG. The hypercall permits
guest control of one or more virtual watchdog timers. The timers have
millisecond granularity. The guest is terminated when a timer
expires.

This patch adds a watchdog driver for these timers, "pseries-wdt".

pseries_wdt_probe() currently assumes the existence of only one
platform device and always assigns it watchdogNumber 1. If we ever
expose more than one timer to userspace we will need to devise a way
to assign a distinct watchdogNumber to each platform device at device
registration time.
