x86 platform drivers: make Dell laptop driver select needed LED support

The driver doesn't check the result and directly uses it as some sort of divisor in some places: msleep(lis3->pwron_delay / lis3lv02d_get_odr()); Under this circumstances, this could very well cause the "divide by zero" exception from above. For now, I fixed it the easiest and most obvious way: Check if the result is sane and if it isn't use a sane default instead. I went for "100" in the latter case, simply because /sys/devices/platform/lis3lv02d/rate returns it on a successful boot.

x86: fix up files really needing to include module.h

These files aren't just exporting symbols -- they are also defining a MODULE_LICENSE etc. so give them the full module.h file. Signed-off-by: Paul Gortmaker
