Subject: [PATCH net 2/6] ice: fix dpll input pin phase_adjust value updates

From: Arkadiusz Kubalewski <arkadiusz.kubalewski@...el.com>

The value of phase_adjust for input pin shall be updated in
ice_dpll_pin_state_update(..). Fix by adding proper argument to the
firmware query function call - a pin's struct field pointer where the
phase_adjust value during driver runtime is stored.

Previously the phase_adjust used to misinform user about actual
phase_adjust value. I.e., if phase_adjust was set to a non zero value and
if driver was reloaded, the user would see the value equal 0, which is
not correct - the actual value is equal to value set before driver reload.

Fixes: 90e1c90750d7 ("ice: dpll: implement phase related callbacks")
