net: ethernet: stmmac: simplify phy modes management for stm32
No new feature, just to simplify stm32 part to be easier to use.
Add by default all Ethernet clocks in DT, and activate or not in function
of phy mode, clock frequency, if property "st,ext-phyclk" is set or not.
Keep backward compatibility
