The periodic work sends dpll_pin_change_ntf() only for direct CGU input pins. SW pins that wrap these inputs never receive change or phase offset notifications, so userspace consumers such as synce4l monitoring SMA pins via dpll netlink never learn about state transitions or phase offset updates. Similarly, ice_dpll_phase_offset_get() reads the SW pin's own phase_offset field which is never updated; the PPS monitor writes to the backing CGU input's field instead. On top of that, when SMA or U.FL pin state changes via PCA9575 GPIO write, the paired pin's state also changes because they share physical signal paths, but no notification is sent for the peer pin. Fix by introducing ice_dpll_pin_ntf(), a wrapper around dpll_pin_change_ntf() that also notifies any registered SMA/U.FL pin whose backing CGU input matches. Replace all direct dpll_pin_change_ntf() calls in the periodic notification paths with this wrapper. Fix ice_dpll_phase_offset_get() to return the backing CGU input's phase_offset for input-direction SW pins. Add ice_dpll_sw_pin_notify_peer() to send a notification for the paired SW pin after PCA9575 writes. The peer notification is called from the dpll_pin_ops callback wrappers after pf->dplls.lock is released, because dpll_pin_change_ntf() sends a netlink message that invokes driver callbacks which acquire the same lock.
