Revert "Input: introduce BTN/ABS bits for drums and guitars"
This reverts commits 61e00655e9cb, 73f8645db191 and 8e22ecb603c8: "Input: introduce BTN/ABS bits for drums and guitars" "HID: wiimote: add support for Guitar-Hero drums" "HID: wiimote: add support for Guitar-Hero guitars" The extra new ABS_xx values resulted in ABS_MAX no longer being a power-of-two, which broke the comparison logic. It also caused the ioctl numbers to overflow into the next byte, causing problems for that. We'll try again for 3.13.
