board: dragonboard410c: upstream DT compat

Use the root compatible strings from upstream Linux, add missing
'#clock-cells' property to the gcc node.

Adjust some of the msm8916/apq8016 drivers to use the correct upstream
compatible properties and DT bindings.

This prepares us to switch to upstream DT in a future patch.
