Subject: [PATCH v2 1/2] net: stmmac: dwmac-mediatek: Fix inverted handling
 of mediatek,mac-wol

The mediatek,mac-wol property is being handled backwards to what is
described in the binding: it currently enables PHY WOL when the property
is present and vice versa. Invert the driver logic so it matches the
binding description.

Fixes: fd1d62d80ebc ("net: stmmac: replace the use_phy_wol field with a flag")
