timekeeping: Lift clocksource cacheline restriction

timekeeping: Lift clocksource cacheline restriction

We cache all hotpath members of a clocksource in the time keeper
core. So there is no requirement in general to cache line align struct
clocksource. Remove the enforces alignment.

That allows users which need to wrap struct clocksource into their own
struct to align the struct without getting extra padding.
