mtd: brcmnand: Fix v7.1 register offsets
commit d267aefc54a28efc5bda7f009598dc83b5f98734 upstream.
The BRCMNAND controller revision 7.1 is almost 100% compatible with the
previous v6.0 register offset layout, except for the Correctable Error
Reporting Threshold registers. Fix this by adding another table with the
correct offsets for CORR_THRESHOLD and CORR_THRESHOLD_EXT.
Fixes: 27c5b17cd1b1 ("mtd: nand: add NAND driver "library" for Broadcom STB NAND controller")
