[PATCH] dts: remove optional docs dependencies

[Luca Vizzarro]

The CI currently does not support the optional DTS docs dependencies. As
a consequence, all of the public docs are always built and deployed without
them.

To simplify the maintenance process, remove the optional docs dependencies
and abandon support.
