Up until now, the external MDIO controller frequency values relied
either on the default ones out of reset or on those setup by u-boot.
Let's just properly specify the MDC frequency in the DTS so that even
without u-boot's intervention Linux can drive the MDIO bus.
Fixes: 0420dde30a90 ("arm64: dts: ls208xa: add the external MDIO nodes")
