m68k: change remaining timers to legacy_timer_tick 

There are nine more machines that each have their own timer interrupt
calling the m68k timer_interrupt() function through an indirect pointer.

This function is now the same as legacy_timer_tick, so just call that
directly and select the corresponding Kconfig symbol.
