Thomas Gleixner 7b7a9175c6 timekeeping: Remove CONFIG_DEBUG_TIMEKEEPING ...

commit d44d26987bb3df6d76556827097fc9ce17565cb8 upstream.

Since 135225a363 timekeeping_cycles_to_ns() handles large offsets which
would lead to 64bit multiplication overflows correctly. It's also protected
against negative motion of the clocksource unconditionally, which was
exclusive to x86 before.

timekeeping_advance() handles large offsets already correctly.

That means the value of CONFIG_DEBUG_TIMEKEEPING which analyzed these cases
is very close to zero. Remove all of it.
