Upcoming changes to the generic vDSO library will mean that the vDSO
datapage will not yet be usable during time_early_init().

Move the initialization to time_init() which is called later. This is
valid as the value of tod_clock_base.tod only changes in stop_machine()
context and both time_init_early() and time_init() are called before
interrupts are enabled.
