Add NAND support on the Armada-8040-DB by adding the same tree as for
the Armada-7040-DB by using the same compatible string
"marvell,armada-8k-nand".

Do not enable the NAND node as enabling it (and changing manually the
proper DPR-76 switch) would disable MDIO from CP1 (and thus disable CPS
Ethernet PHY).
