Subject: [PATCH] arm: support big-endian for the virt architecture

This architecture, used for running in QEMU, runs just fine when
compiled in big-endian mode. So enable it. This is enabled in exactly
the same way that it is for other platforms (such as vexpress) that also
support big-endian mode in QEMU successfully.

Personally, I'm using this as part of WireGuard's CI, and patching
kernels to include this is a bit annoying. Any chance this can get into
4.19?
