topstar-latop: ignore 0x82 event
Event 0x82 is emitted whenever a backlight event happens (brightness change, backlight on/off). For instance, when display is switched off after a timeout, event 0x82 is emitted, and along with it a keypress which switches the display back on again. This patch adds 0x82 to the event ignore list so that the display stays off when it is automatically switched off.
