Subject: [PATCH] arm64: dts: ls1028a-qds: define mdio slots for networking options

The ls1028a QDS board support different pluggable PHY cards. Define the
nodes for these slots to be updated at boot time with overlay according
to board setup.

This fixes:
=> tftp $fdt_addr_r fsl-ls1028a-qds.dtb && tftp $fdt_ovr_addr_r fsl-ls1028a-qds-85bb.dtb
=> fdt addr $fdt_addr_r && fdt resize 0x100000 && fdt apply $fdt_ovr_addr_r
failed on fdt_overlay_apply(): FDT_ERR_NOTFOUND
