s390/time: remove select CLOCKSOURCE_VALIDATE_LAST_CYCLE again

Browse Source 
Sven Schnelle reported that setting CLOCKSOURCE_VALIDATE_LAST_CYCLE
doesn't make sense: even if our tod clock overflows delta calculation
(now - last) with unsigned 64 bit values will still be correct.

Therefore revert commit 555701a714 ("s390/time: select
CLOCKSOURCE_VALIDATE_LAST_CYCLE").
