HID: lenovo: Merge tpkbd and cptkbd data structures
Merge the tpkbd and cptkbd data structures, into a single unified structure instead of having a separate data structure per keyboard type. This is a preparation patch for making the tpkbd LED functions more generic, so that they can be re-used for supporting the LEDs on the Thinkpad 10 ultrabook keyboard.
