[PATCH edk2-platforms 4/5] Silicon/SynQuacer/PlatformDxe: add menu option to select mezzanine

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

96boards mezzanines are not runtime discoverable, so it is up to the
user to tell the firmware what is connected. So add a pulldown entry
that allows a selection to be made: note that boards are only expected
to have a single LS connector, so a pulldown is appropriate here.

If Secure96 has been selected by the user, install the associated GUID
as a protocol, which the Secure96Dxe (which installs the DT overlay into
the device tree) has a depex on.
