arm64: dts: mediatek: Set mediatek,mac-wol on DWMAC node for all boards

Due to the mediatek,mac-wol property previously being handled backwards
by the dwmac-mediatek driver, its use in the DTs seems to have been
inconsistent.

Now that the driver has been fixed, correct this description. All the
currently upstream boards support MAC WOL, so add the mediatek,mac-wol
property to the missing ones.
