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.

Convert those documents and prepare them to be part of the kernel
API book, as most of the stuff there are related to the
Kernel interfaces.
Still, in the future, it would make sense to split the docs,
as some of the stuff is clearly focused on sysadmin tasks.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
