Fix build errors when CONFIG_INPUT is disabled (shortened list):

olpc-xo1-sci.c:(.text+0x1aee6): undefined reference to `input_event'
olpc-xo1-sci.c:(.text+0x1b077): undefined reference to `input_unregister_device'
olpc-xo1-sci.c:(.text+0x1b081): undefined reference to `input_free_device'
arch/x86/built-in.o:olpc-xo1-sci.c:(.text+0x1b270): more undefined references to `input_event' follow
olpc-xo1-sci.c:(.devinit.text+0x155): undefined reference to `input_allocate_device'
olpc-xo1-sci.c:(.devinit.text+0x1a4): undefined reference to `input_register_device'
