tools headers kvm: Sync ARM UAPI headers with the kernel sources

To sync with the changes made in 85bd0ba1ff98 ("arm/arm64: KVM: Add PSCI
version selection API"), that do not cause any changes in the tools,
just to silence the build warning:

  Warning: Kernel ABI header at 'tools/arch/arm/include/uapi/asm/kvm.h' differs from latest version at 'arch/arm/include/uapi/asm/kvm.h'
  Warning: Kernel ABI header at 'tools/arch/arm64/include/uapi/asm/kvm.h' differs from latest version at 'arch/arm64/include/uapi/asm/kvm.h'
