arm64: dts: ls1088a: specify clock frequencies for the MDIO controllers
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.
