hrtimers: Provide schedule_hrtimeout for CLOCK_REALTIME
The current version of schedule_hrtimeout() always uses the
monotonic clock. Some system calls such as mq_timedsend()
and mq_timedreceive(), however, require the use of the wall
clock due to the definition of the system call.
This patch provides the infrastructure to use schedule_hrtimeout()
with a CLOCK_REALTIME timer.
