The software Hamming ECC engine stores the nsteps variable in its own
private structure while it is also exported as a public ECC field.
Let's get rid of the redundant private one and let's use the
nand_ecc_context structure when possible.

This code is meant to be reused by the SPI-NAND core. Now that the
driver has been cleaned and reorganized, use a generic ECC engine
object to store the driver's data instead of accessing members of the
nand_chip structure. This means adding proper init/cleanup helpers.

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.

The include file pretends being the header for "ECC algorithm", while
it is just the header for the Hamming implementation. Make this clear
by rewording the sentence.
Do the same with the module description.
