zeroplus: Only report supported samplerates. 

The currently supported model LAP-C(16032) doesn't support the
samplerates 150MHz and 200MHz which some of the other models have.

Thus, do not report these samplerates to the frontends. E.g. sigrok-cli
should not show them via --show and GUIs should not list them in their
"Samplerates" drop-down.
