kvm_types.h is mandatory in include/asm-generic/Kbuild so having it
in another Kbuild file causes a warning. Remove it from the arch/
Kbuild file to fix the warning.

This should go via perf/core from the tip tree, since Peter's not-yet upstream
commit 01122b89361e ("perf: Use EXPORT_SYMBOL_FOR_KVM() for the mediated
APIs") adds the mandatory-y statement to include/asm-generic/Kbuild.
Peter?
