[U-Boot] [PATCH] net: allow fix speed for FEC driver

[Stefano Babic]

Sometimes the MII is not used at all - for example,
when the controller is connected to a switch with
a fixed speed, and the MDC/MDIO signal are used
for something else.

Allow to set a fixed speed in the FEC driver
without relying on the autonegotiation.

The use case is the FEC connected to a Switch
without using MDIO / MDC. The FEC has no way to
get the speed.
