Subject: [PATCH 2/3] 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.
Fixes: bbe75af7b092 ("arm64: dts: ls1088a: add external MDIO device nodes")
