USB: ati_remote.c: autorepeat fix
When HZ is set to 250 (new default) or 100, the time span during which repeated events from the device are ignored could be too small due to ms->jiffies rounding. This causes the auto repeat to kick in early making it impossible for the user to generate individual press/release events. Increate the timeout to compensate.
