Petteri Aimonen 1825f9534c adjtime: Rewrite implementation to work for RTC and tickless kernel
Previous adjtime() implementation was limited to adjusting system
timer tick period. This commit reimplements the internals to use
a kernel watchdog timer. Platform-independent part of the code now
works also for adjusting hires RTC and tickless timer rate.

User code facing API is unchanged. Architecture code API has changed:
up_adj_timer_period() is replaced by up_adjtime().

Other improvements:

- Support query of remaining adjustment by passing NULL to first
  argument of adjtime(). This matches Linux behavior.

- Improve resolution available for architecture driver, previously
  limited to 1 microsecond per tick. Now 1 nanosecond per second.
