platform/x86: dell-smbios: Auto-select as needed

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.

Also select DCDBAS as needed, instead of depending on it, so that the Dell driver options are always visible.

As a clean-up, I removed the "default n" statements as they are not needed (n is the default default.)

Changes since v2:
 * Change the subject as suggested by Andy.
 * Remove "default n" as suggested by Andy.
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.
