bsps/pc386: Fix Clock_isr for SMP

• Do not forward Clock_isr through Clock_driver_support_at_tick as this

will cause every processor to send IPIs with Clock_isr therby creating
an infinie loop

• Instead the processor handling the clock interrupt causes all other

processors to call rtems_timecounter_tick to update their tick count
