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.

watchdog: Add Realtek Otto watchdog timer

Realtek MIPS SoCs (platform name Otto) have a watchdog timer with
pretimeout notifitication support. The WDT can (partially) hard reset,
or soft reset the SoC.

This driver implements all features as described in the devicetree
binding, except the phase2 interrupt, and also functions as a restart
handler. The cpu reset mode is considered to be a "warm" restart, since
this mode does not reset all peripherals. Being an embedded system
though, the "cpu" and "software" modes will still cause the bootloader
to run on restart.

It is not known how a forced system reset can be disabled on the
supported platforms. This means that the phase2 interrupt will only fire
at the same time as reset, so implementing phase2 is of little use.

watchdog: Remove BCM63XX_WDT

Now that we can utilize the BCM7038_WDT driver, remove that one which
was not converted to the watchdog APIs. There are a couple of notable
differences with how the bcm7038_wdt driver proceeds:

- bcm63xx_wdt would register with the ad-hoc BCM63xx hardware timer API,
but this would only be used in order to catch the interrupt *before* a
SoC reset and make the kernel "die"

- bcm6xx_wdt would register a software timer and kick it every second in
order to pet the watchdog, thus offering a two step watchdog process.
This is not something that is brought over to the bcm7038_wdt as it is
deemed unnecessary. If user-space cannot pet the watchdog, but a
kernel timer can, the system is still in a bad shape anyway.

bcm7038_wdt is simpler in its behavior and behaves as a standard
watchdog driver and is not making use of any specific platform APIs,
therefore making it more maintainable and extensible.
