Thomas Gleixner d44d26987b timekeeping: Remove CONFIG_DEBUG_TIMEKEEPING
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.
