srd: onewire_link: Annotations shouldn't be ALLCAPS. While states in the PD should be ALLCAPS per guidelines (for consistency), the annotations that a PD outputs (and are shown in a console via sigrok-cli or in a GUI) should be "normal" human-readable text/formatting usually, i.e. not ALLCAPS.
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).
