[PATCH] arm64: dts: r8a7795: Add GIC-400 virtual interfaces

[Dirk Behme]

Besides the distributor and the CPU interface the GIC-400 additionally
supports the virtual interface control blocks and the virtual CPU interfaces.

Add the physical base addresses and size for these.

See

http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0471b/index.html
-> 3.2. GIC-400 register map

and Linux kernel's

Documentation/devicetree/bindings/interrupt-controller/arm,gic.txt

for more details.

Our R-Car chip is out-of-mapping.
Geert had indicated it in
http://thread.gmane.org/gmane.linux.ports.sh.devel/49751/focus=51544
And we have no answer about it I think

Could you point us to the code where you think our out-of-mapping 
doesn't work?

Best regards
