mtd: nand: fsl_ifc: Read ECCSTAT0 and ECCSTAT1 registers for IFC 2.0
commit 6b00c35138b404be98b85f4a703be594cbed501c upstream.
Due to missing information in Hardware manual, current
implementation doesn't read ECCSTAT0 and ECCSTAT1 registers
for IFC 2.0.
Add support to read ECCSTAT0 and ECCSTAT1 registers during
ecccheck for IFC 2.0.
Fixes: 656441478ed5 ("mtd: nand: ifc: Fix location of eccstat registers for IFC V1.0")
