Subject: [PATCH v3 5/5] arm64: dts: ls208x: remove NXP Erratum A008585 from LS2088A.

From: Pankaj Bansal <pankaj.bansal@....com>

NXP Erratum A008585 affects A57 core cluster used in LS2085 rev1.
However this problem has been fixed in A72 core cluster used in LS2088.
Therefore remove the erratum from LS2088A. Keeping it only in LS2085.
