Input: restore EV_ABS ABS_RESERVED 



[ Upstream commit c201e3808e0e4be9b98d192802085a9f491bd80c ]

ABS_RESERVED was added in d9ca1c990a7 and accidentally removed as part of
ffe0e7cf290f5c9 when the high-resolution scrolling code was removed.

/*

 * 0x2e is reserved and should not be used in input drivers.

 * It was used by HID as ABS_MISC+6 and userspace needs to detect if

 * the next ABS_* event is correct or is just ABS_MISC + n.

 * We define here ABS_RESERVED so userspace can rely on it and detect

 * the situation described above.
