As discussed, v2 moves TOD set/get functions to the setone/getone interface.
A high byte is also provided to account for future expansion.

Provide KVM_REG_S390_TOD and KVM_REG_S390_TOD_HIGH registers on s390 for
managing guest Time Of Day clock value.
KVM_REG_S390_TOD_HIGH is presently always set to 0. In the future it will
contain a high order expansion of the tod clock value after

Enable KVM_SET_CLOCK and KVM_GET_CLOCK Ioctls on S390 for managing guest TOD
clock value.
we add the KVM_CLOCK_FORWARD_ONLY flag to indicate to KVM_SET_CLOCK that the
given clock value should only be set if it is = the current guest TOD clock
value
