Change it back to use AT803X_INTR_ENABLE_WOL for determining the WoL status which is applicable on all chips supporting wol. Also update the at803x_set_wol() function to only update the 1588 register on chips having it. After this change, disabling wol at probe from d7cd5e06c9dd ("net: phy: at803x: disable WOL at probe") is no longer needed. So that part is removed.
