[PATCH net v6 0/2] ice: fix missing dpll notifications for SW pins

[Petr Oros <poros@redhat.com>]

The SMA/U.FL pin redesign never propagated dpll notifications to the
software-controlled pin wrappers.  This series fixes that by adding
peer notification for paired SMA/U.FL pins and by wrapping
dpll_pin_change_ntf() calls in the periodic work to also cover SW pins.

Patch 1 exports __dpll_pin_change_ntf() so ice can send peer
notifications from callback context where dpll_lock is already held.

Patch 2 fixes the notification gaps: periodic work HW-to-SW
propagation, SW-to-SW peer notification on PCA9575 routing changes,
and SW pin phase offset reporting.

v6:
 - fix deadlock reported by Michal Schmidt: dpll_pin_change_ntf() in
   peer notification was called with dpll_lock held, causing deadlock.
   Move the peer notification calls out of ice_dpll_sma_direction_set()
   and ice_dpll_ufl_pin_state_set() into their dpll_pin_ops callback
   wrappers, after pf->dplls.lock is released, and use
   __dpll_pin_change_ntf() because dpll_lock is still held by the dpll
   netlink layer (dpll_pin_pre_doit).
