Subject: [PATCH 06/13] net: phy: mediatek: Hook LED helper functions in
 mtk-ge.c

We have mtk-phy-lib.c now so that we can use LED helper functions in
mtk-ge.c(mt7531 part). It also means that mt7531/mt7981/mt7988's
Giga ethernet phys share almost the same HW LED controller design.
Also, add probe function for mt7531 so that it can initialize LED state.
