[PATCH] kvm: move kvmclock initialization inside kvm_guest_init

[Glauber Costa <gcosta@redhat.com>]

It makes no sense for the clock initialization to be
hanging around in setup_32.c when we have a generic kvm guest
initialization function available. So, we move kvmclock_init()
inside such a function, leading to a cleaner code.
