Lars-Peter Clausen 139876d28a up_clock_mon: Remove extra hold register 
Currently the clock monitor features a hold register in the monitored clock
domain. This old register is used to store a instantaneous copy of the
counter register. The value in the old register is then transferred to the
monitoring domain. Since the counter is continuously counting it is not
possible to directly transfer it since that might result in inconsistent
data.

Instead stop the counter and hold the registers stable for a duration that
is long enough for the monitoring domain to correctly capture the value.
Once the value has been transferred the counter is reset and restarted for
the next iteration.

This allows to eliminate the hold register, which slightly reduces
utilization.

The externally visible behaviour is identical before and after the patch.
