Right now, SET CLOCK called in the guest does not properly take care of
the epoch index, as the call goes via the old kvm_s390_set_tod_clock()
interface. So the epoch index is neither reset to 0, if required, nor
properly set to e.g. 0xff on negative values.
Fix this by providing a single kvm_s390_set_tod_clock() function. Move
Multiple-epoch facility handling into it.
