Input: i8042 - add unmask_kbd_data option
A big problem with the current i8042 debugging option is that it outputs data going to and from the keyboard by default. As a result, many dmesg logs uploaded by users will unintentionally contain sensitive information such as their password, as such it's probably a good idea not to output data coming from the keyboard unless specifically enabled by the user.
