timekeeping: Clean up ktime_get_real_ts64

Browse source 
In a move to make ktime_get_*() the preferred driver interface into the
timekeeping code, sanitizes ktime_get_real_ts64() to be a proper exported
symbol rather than an alias for getnstimeofday64().

The internal __getnstimeofday64() is no longer used, so remove that
and merge it into ktime_get_real_ts64().
