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
version 3:
Add acked from Alexandre Torgue
Rebased on top of v5.7-rc2
