[PATCH 4/7] HID: input: add mapping for Expose/Overview key

[Dmitry Torokhov]

According to HUTRR77 usage 0x29f from the consumer page is reserved for
the Desktop application to present all running userâs application windows.
Linux defines KEY_SCALE to request Compiz Scale (Expose) mode, so let's
add the mapping.
