hw/arm/stellaris: Remove board-creation reset of STELLARIS_SYS

Now that the watchdog device uses its Clock input rather than being
passed the value of system_clock_scale at creation time, we can
remove the hack where we reset the STELLARIS_SYS at board creation
time to force it to set system_clock_scale.  Instead it will be reset
at the usual point in startup and will inform the watchdog of the
clock frequency at that point.
