mtd: nand: ecc-hamming: Rename the exported functions
Prefix by ecc_sw_hamming_ the functions which should be internal only
but are exported for "raw" operations.
Prefix by nand_ecc_sw_hamming_ the other functions which will be used
in the context of the declaration of an Hamming proper ECC engine
object.
