[RFC PATCH edk2-platforms 6/6] Platform/Socionext/DeveloperBox: add SCP firmware image to capsule

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

Modify the .FDF definitions describing the Flash Device and the
capsule payload so that the SCP firmware can be updated along with
the ARM Trusted Firmware and EDK2 code.

Note that this does not increase the likelihood some kind of recovery
is needed when a capsule update fails: the NOR layout has been updated
to allow the serial flasher to execute even if the SCP firmware has
been corrupted, and a failed flash of just UEFI already requires such
recovery anyway.

Since this constitutes a backward incompatible changes as far as
capsule update is concerned, add a provision for setting the minimum
supported firmware version via the build command line.
