arm64: dts: lx2160a: specify clock frequencies for the MDIO controllers

Browse Source 
[ Upstream commit c126a0abc5dadd7df236f20aae6d8c3d103f095c ]

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.
