Commit 3ab72f9156bb "dt-bindings: add GIC-400 binding" added the
"arm,gic-400" compatible string, but the corresponding IRQCHIP_DECLARE
was never added to the gic driver.

Therefore add the missing irqchip declaration for it.

Removed additional empty line and adapted commit message to mark it
as fixing an issue.

As I really need this, I took the liberty of adapting the patch accordingly
to make it apply on top of the current irqchip/for-next (or urgent) and
explicitly state the fixed issue. Hope that is ok

Applied to irqchip/urgent with Will's Ack and Cc'd to stable for v3.14+

While this is a fix that we should have, I'm not certain I see why this
is urgent. A dt can already have:

	compatible = "arm,gic-400", "arm,cortex-a15-gic";

Which will work _today_, before this patch. If we need to treat the A15
GIC string differently, we'll have to ensure we support the GIC 400
string first.

Thanks,
Mark.
