[PATCH v2 0/3] KVM: arm64: fix warnings in W=1 build

Building arch/arm64/kvm/ with W=1 spills out a lot of warnings. When
changing stuff I try to use as much tooling as possible to make sure
that I don't screw up - having a clean baseline imho helps with that.

With the first 2 patches applied make W=1 arch/arm64/kvm/ runs without
warnings for me (fedora userspace, upstream linux after kvm merge).
Patch 3 gets rid of sparse lock warnings in arch/arm64/kvm/vgic/.

Patch 1 now just adds -Wno-override-init to the cflags of the affected
files. Alternatives would be to add this to the whole subdir or
reintroduce the flag for higher warn levels..
