srd: onewire_link/network: Fix annotations, small cleanups.
The annotation types are 'Text' and 'Warnings', not 'Link' etc. as the annotations of the onewire_link PD (for example) are already clearly from the link layer. The annotation types should be different things/formats of a specific PD's annotation output instead (like "Celsius" / "Kelvin" for some temperature sensor, for example).
