timestamps: COLLECT_TIMESTAMPS is mostly optional
It is a user-visible option and enabled by default for ARCH_X86,
some consider it as debugging aid only. Therefore platform design
should not depend on it.
It must remain selected with CHROMEOS and boards are allowed
to explicitly select it as well.
For siemens/mc_bdx1,mc_aplX boot time will be increased due
the use of get_us_since_boot() with COLLECT_TIMESTAMPS=n.
When unable to determine if N seconds has elapsed from boot,
this turns into a delay of N seconds.
