[PATCH edk2-platforms v4 25/34] Silicon/SynQuacer: add description of EXIU to the device tree

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

Add a DT node for the external interrupt unit (EXIU), which handles
interrupts from GPIO lines. We need OS support for this for things
like PHY interrupts and a 'wake' button.
