[PATCH v2 0/2] clocksource: don't suspend/resume when unused

[Alexandre Belloni]

This is a quite naive implementation to track whether a clocksource is enabled.
I chose not to add a member in struct clocksource and use a flag instead.

I found that timekeeping.c is the only consumer for clocksource and I converted
it to use clocksource_enable and clocksource_disable.

Changes in v2:
 - removed the check on enable in timekeeping.c to ensure all clocksources are
   going through clocksource_enable
 - rework clocksource_enable to set CLOCK_SOURCE_USED when enable is successful
   if present

  clocksource: track usage
  clocksource: don't suspend/resume when unused
