ar71xx: fix invalid pointer dereference in c60_nand_scan_fixup()
Since Linux 4.6, mtd->priv no longer points to the NAND specific
structure. Under 4.9 it contains NULL, thus using it to access
the fields of the nand_chip structure causes an invalid pointer
dereference.
Update the code to use the mtd_to_nand() helper under 4.9 to obtain
the address of the chip specific data.
Compile tested only.
