Subject: [PATCH 1/2] Make WMI be selected automatically when needed

Many different modules depend on WMI. In Kconfig, some used to "depend"
on it, while others "selected" it. As WMI by itself is useless and more
like a library, it's easier for the user to have it automatically
selected whenever needed. It's especially true for options in completely
different places (like LEDS_DELL_NETBOOKS). So we consistently "select"
it.
