mtd: nand: fsl_ifc: Read ECCSTAT0 and ECCSTAT1 registers for IFC 2.0

Browse source 
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: 656441478e ("mtd: nand: ifc: Fix location of eccstat registers for IFC V1.0")
