Subject: [PATCH 4.14 090/125] mtd: rawnand: brcmnand: fix CS0 layout

From: Álvaro Fernández Rojas <noltari@...il.com>

commit 3d3fb3c5be9ce07fa85d8f67fb3922e4613b955b upstream.

Only v3.3-v5.0 have a different CS0 layout.
Controllers before v3.3 use the same layout for every CS.

Fixes: 27c5b17cd1b1 ("mtd: nand: add NAND driver "library" for Broadcom STB NAND controller")
