Message type for PM_ time-related calls

Browse Source 
- Message type for PM_CLOCK_SETTIME, PM_CLOCK_GETTIME,
   PM_CLOCK_GETRES, PM_GETTIMEOFDAY, PM_SETTIME.

 - Small adaptation, message only transfert sub-second time in
   nanoseconds, instead of both nano- and micro-seconds. Conversion
   is done in userland, as required.
