* include/nuttx/serial: Move all serial-driver related files from include/nuttx to
include/nuttx/serial.
+ * include/nuttx/clock.h and sched/clock_initialize.c: Add a new OS interface
+ called clock_sychronize() that can be used to re-synchronize the NuttX
+ system time with a hardware RTC. This function is called normally at power
+ up but may also need to be called when recovering from certain low-power
+ usage states where the system time is no longer accurate.
