net: phy: at803x: fix the wol setting functions
[ Upstream commit e58f30246c35c126c7571065b33bee4b3b1d2ef8 ]
In commit 7beecaf7d507 ("net: phy: at803x: improve the WOL feature"), it
seems not correct to use a wol_en bit in a 1588 Control Register which is
only available on AR8031/AR8033(share the same phy_id) to determine if WoL
is enabled. 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 commit
d7cd5e06c9dd ("net: phy: at803x: disable WOL at probe") is no longer
needed. Change it to just disable the WoL bit in 1588 register for
AR8031/AR8033 to be aligned with AT803X_INTR_ENABLE_WOL in probe.
