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
