HID: driver for Twinhan USB 6253:0100 remote control
Add explicit key mappings for TwinHan USB HID remote control. All dummy Ctrl, Alt, Meta, ... key press/release events generated by the remote are silenced by "unmapping" them. This makes Power and Volume keys single-key and strips the regular (even while idle) key release events for Ctrl, Alt, Meta, ...
