Sansa AMS: Revert r21177 : the timer frequency is used by the user timer (example: metronome will be twice too fast)

Instead use a private KERNEL_TIMER_FREQ define which is dependant on HAVE_SCROLLWHEEL
Comment that call_tick_tasks() will read the scrollwheel
Remove the unneeded volatile type qualifier from poll_scrollwheel
