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

Browse Source 
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.
