sun4m: fix slavio timer RUN/STOP bit
The sun4m architecture has one 'system' timer and one timer per CPU.
The CPU timers can be configured in two modes:
* 22 bits Counter/Timer. Periodic interrupts.
* 54 bits User timer. For profiling. In this mode, the Run/Stop bit
controls the timer.
The run/stop bit controls the timer only when it is in "User" mode, but
its state shall be persistent.
