arm64: dts: amd/seattle: Move and simplify fixed clocks

The fixed clocks are not part of "simple-bus", so move them out of the
bus to the top-level. In the process, use the preferred node names of
"clock-<freq>". There's also little reason to have multiple fixed
clocks at the same frequencies, so remove them keeping the labels
to minimize the change.
