Subject: ARM: dts: Specify the NAND ECC scheme explicitly on Armada 385 DB board

ARM: dts: Specify the NAND ECC scheme explicitly on Armada 385 DB board
The factory bootloader on A385-DB boards expect the ECC strength to be
4 bits over 512 bytes. Hence, we need to specify this in the devicetree,
to prevent the kernel from assuming any different ECC scheme.
