Subject: mtd: brcmnand: Fix v7.1 register offsets

From: Florian Fainelli <f.fainelli@gmail.com>

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.
