Gregory Nutt 0863e771a9 Revert "sched/clock/clock_initialize.c: clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet." ...

This reverts commit 2bc709d4b9.

Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case.  However, this change has the side-effect of breaking every implementation of tickless mode:  After this change the tickless timer structures are used before they are initialized in clock_inittime().  Initialization happens later when up_initialize is called() when arm_timer_initialize().

Since the tickless mode timer is very special, one solution might be to

1. Rename xxx_timer_initialize to up_timer_initialize
2  Move up_timer_initialize to include/nuttx/arch.h
3.  Call it from clock subsystem instead up_initialize

Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).

For now, however, we just need to revert the change.
