ARM: mvebu: Netgear RN102: Use Hardware BCH ECC

commit ace85781 upstream.

The bootloader on the Netgear ReadyNAS RN102 uses Hardware BCH ECC
(strength = 4), while the pxa3xx NAND driver by default uses
Hamming ECC (strength = 1).

This patch changes the ECC mode on these machines to match that
of the bootloader and of the stock firmware. That way, it is
now possible to update the kernel from userland (e.g. using
standard tools from mtd-utils package); u-boot will happily
load and boot it.

Fixes: 92beaccd ("ARM: mvebu: Enable NAND controller in ReadyNAS 102 .dts file")
