[PATCH 0/4] ArmPkg, ArmPlatformPkg: watchdog driver cleanup

[Ard Biesheuvel <ard.biesheuvel@linaro.org>]

This series cleans up the code of the two watchdog drivers we have for
ARM systems, and brings them in compliance with the PI spec, which
specifies that the default action of the watchdog can be overridden
by registering a handler.

Note that the TC2 code in edk2-platforms will have to be brought up to
date. The SP805 on the FVP model seems terminally broken (it is 'wired'
to the 24 MHz APB clock instead of the 32 kHz WDOG clock, so I'll switch
that one over to use the SBSA watchdog instead)
