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, ...
