KVM: Move declaration of kvm_cpu_dirty_log_size() to kvm_dirty_ring.h

Browse Source 
Not all architectures like ARM64 need to override the function. Move
its declaration to kvm_dirty_ring.h to avoid the following compiling
warning on ARM64 when the feature is enabled.

  arch/arm64/kvm/../../../virt/kvm/dirty_ring.c:14:12:        \
  warning: no previous prototype for 'kvm_cpu_dirty_log_size' \
  [-Wmissing-prototypes]                                      \
  int __weak kvm_cpu_dirty_log_size(void)
