For anyone wondering why we have two strings here:
The SBC board is made up of a SoM and a board with the connectors.
The SoM could be used standalone so we might as well have a compatible
for it too.
We have some dtsis for the SoM but really those could be built as is
to support someone using the SoM on it's own.

For anyone wondering:
The som2d01 can come with an SSD201 (64MB DDR2 integrated) or SSD202D
(128MB DDR3 integrated) and they need different fixed regulators for
the DDR supply.
So we have a common dtsi and then override the regulator in another
layer of dtsi for the SSD202D version.
Thinking about it now I think we can drop common from the file name.
