arm64: next-20171114 GICv4 build failure

[Andreas Färber]

Hello,

Yesterday's and today's linux-next fail to build for me on arm64 with
the following warnings and errors:

I'm guessing there's some Kconfig or guard issue? No GICv4 options
popped up during oldconfig. And my arm config still builds fine.

Thanks,
