#1414710 — [PATCH 2/2] ARM: BCM5301X: Fix NAND ECC parameters for D-Link DIR-885L

This device uses BCH-1 instead of BCH-8. This fixes ECC errors and makes
NAND usable with brcmnand.

As suggested recently, the new file uses BSD-compatible license. I was
considering BSD [23]-clause license and Hauke said he likes ISC which is
even simpler, so I picked this one.
