From: Ard Biesheuvel <ardb@kernel.org>
The DumpVars() routine is called directly and via an event notification
callback, and the latter therefore defines the function's prototype,
even though the arguments are unused.
We will introduce another callback into this logic, but via a reset
notifier, which has yet another prototype. So to keep things tidy, drop
the formal parameters from DumpVars() and invoke it via a helper
function that discards the arguments when called as a event notification
callback. We will do the same for the reset notification once that
functionality gets added.

In addition to setting up the home grown reset notification, register
with the generic EFI protocol that does the same. This event is
triggered from the reset runtime implemented in MdeModulePkg, to which
we will be switching the RPi platforms in a subsequent patch.

Duplicate the logic that is triggered on a system reset into the
platform boot manager driver, and hook it up to the EDK2 platform
specific reset notification driver. This is supported by generic EDK2
code in MdeModulePkg, allowing us to retire the platform-specific
EfiResetSystemLib implementation in a subsequent patch. This is needed
because this library class and its only user ResetRuntimeDxe in
EmbeddedPkg are deprecated and are going to be removed.

Drop the reference to the special reset runtime DXE driver in
EmbeddedPkg, and move to the one in MdeModulePkg shared between all
architectures. This version implements reset notifications, allowing us
to retire the home grown version of that functionality in a subsequent
patch.
Add depexes to the components that rely on the reset notification
protocols to ensure that they are not dispatched before those protocols
are made available by the reset runtime DXE driver.

The first couple are DCE time/mac UUIDs with the MAC address fuzzed, no?
Initially I assumed this coudn't be the case because I would have
expected the timestamp (2016-06-13 21:57:59, which looks almost
reasonable) to vary, but i'm guessing they were generated, and then
someone didn't want their mac in the pubic so they fuzzed it a couple
times rather than generating completely new IDs. Some of the others
though, maybe a BE/LE UUID/GUID manual conversion (or not) problem...
Anyway, I will spin it up in a day or two on real hardware, but right
now its all torn down in boxes because i've moved.

I ran into some issues with dispatch order - the added depexes prevent
the varblockservicedxe from being dispatched before the
VariableRuntimeDxe, which results in a crash.
