Add support for Deltaco and Smatrul dual smartplugs.

Issue #527, #521

Merged into a single config, as the dp assignments follow the standard
layout, and probably match many other devices if we are lenient about
which are optional.  Otherwise smartplug variations with only minor
differences are multiplying too quickly.

Should also cover #480 except for the different child lock dp
assignment, and additional master switch.
