The HW reports the currently selected reference in the dpll_refsel_status register regardless of the DPLL mode. Use this to delete zl3073x_dpll_selected_ref_get() and have callers read the register directly via the cached channel state. Simplify zl3073x_dpll_connected_ref_get() to check refsel_state for LOCK directly and return the reference index, changing the return type from int to u8. The redundant ref_is_status_ok check is removed since the DPLL cannot be in LOCK state with a failed reference. In zl3073x_dpll_mode_set(), replace the selected_ref_get() call with zl3073x_chan_refsel_ref_get() to read the currently selected reference directly from the cached channel state.
