sparc32, leon: Remove separate "ticker" timer for SMP
This reduces the need from two timers to one timer. Moreover, without this patch, when the "ticker" timer triggers timer_cs_read via tick_periodic it reads the value of the usual timer it can get an wrapped timer value without timer_cs_internal_counter having been updated leading to the clock going backwards. This effectively hangs one cpu that gets stuck in update_wall_time with an offset slightly smaller than 0xffffffffffffffff. Signed-off-by:Andreas Larsson <andreas@gaisler.com> Signed-off-by:
