Update mtd-abi.h and use new NAND ECC functionality
The NAND rework exposes more information to userspace and
has a different mechanism to read raw FLASH contents without
ECC. Update nanddump and nandwrite. Use the new ECC statistics
ioctl to inform the user about corrected and uncorrectable
bitflips.
