Subject: [PATCH v2] dell-wmi, dell-laptop: hide dell-smbios

Dell-smbios is a helper module, it serves no purpose on its own, so
do not present it as an option to the user. Instead, select it
automatically whenever a driver which needs it is selected.

Changes since v1:
 * Select DCDBAS instead of depending on it. This is more
   user-friendly and avoids the confusing transitive dependencies
   which Pali didn't like.
