Subject: [PATCH 07/11] fix: ARM64: dts: cp110: Switch to 8-bit ECC NAND setting

From: Konstantin Porotchkin <kostap@...vell.com>

All A7K/A8K boards are using NAND chip that supports
8 bit ECC strength. Using lower ECC strength is not recommended
by the flash manufacturer and may cause data corruption.
This patch changes the nand-ecc-strength value from 4 to 8.
