dpll: zl3073x: clean up esync get/set and use zl3073x_out_is_ndiv()

Return -EOPNOTSUPP early in esync_get callbacks when esync is not
supported instead of conditionally populating the range at the end.
This simplifies the control flow by removing the finish label/goto
in the output variant and the conditional range assignment in both
input and output variants.

Replace open-coded N-div signal format switch statements with
zl3073x_out_is_ndiv() helper in esync_get, esync_set and
frequency_set callbacks.
