[PATCH edk2-platforms v4 04/34] Silicon/SynQuacer: implement a platform DXE driver

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

This implements a driver that will take care of platform specific
initialization, such as declaring non-discoverable devices, and
installing the device tree blob as a configuration table.
