This series enables Ethernet support on STiH407 family reference design
boards.

These boards use the RTL8367 Switch as PHY.
As it is previously configured by the bootloader, we declare it as a fixed
link.

These new re-timing values provides a better stability on Ethernet link.

STiH407 family uses the Synopsys IP.

These boards are mounted with Realtek RTL8367 switch.
We consider the bootloader will have intiliazed the switch before jumping into
the kernel, so we declare it as a fixed link.
