Revert "globals: Allow global properties to be optional"

This reverts commit d7741743f4f3d2683d1bb6938f88dc0167c21afa.

Relying on setting properties on parents types which may not
be relevant to certain sub-classes had unexpected side-effects
causing bugs in device config defaults. It is preferrable to
be explicit about which devices get which properties, even if
this needs repetition.
