Daniel P. Carvalho 9b9423a638 sched/clock: update wall time on tickless tick and support slew limit PPM 
1. nxsched_process_timer: call clock_update_wall_time() under
   CONFIG_CLOCK_TIMEKEEPING so that wall time is updated on timer
   events during tickless operation.

2. clock_timekeeping_get_wall_time: call clock_update_wall_time()
   before sampling the base and counter.

3. clock_timekeeping: allow overriding NTP_MAX_ADJUST with
   CONFIG_CLOCK_ADJTIME_SLEWLIMIT_PPM if configured.

4. Use clock_t consistently for counter values in clock_timekeeping.c.
