Originally, commit d7157ff49a5b ("mtd: rawnand: Use the ECC framework
user input parsing bits") kind of broke the logic around the
initialization of several ECC engines.
Unfortunately, the fix (which indeed moved the ECC initialization to
the right place) did not take into account the fact that a different
ECC algorithm could have been used thanks to a DT property,
considering the "Hamming" algorithm entry a configuration while it was
only a default.
Add the necessary logic to be sure Hamming keeps being only a default.

The probe function is only supposed to initialize the controller
hardware but not the ECC engine. Indeed, we don't know anything about
the NAND chip(s) at this stage. Let's move the logic initializing the
ECC engine, even pretty simple, to the ->attach_chip() hook which gets
called during nand_scan() routine, after the NAND chip discovery. As
the previously mentioned logic is supposed to parse the DT for us, it
is likely that the chip->ecc.* entries be overwritten. So let's avoid
this by moving these lines to ->attach_chip().

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().
Let's stop using nand_release() by calling mtd_device_unregister() and
nand_cleanup() directly.

nand_cleanup() is supposed to be called on error after a successful
call to nand_scan() to free all NAND resources.
There is no real Fixes tag applying here as the use of nand_release()
in this driver predates by far the introduction of nand_cleanup() in
commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible, hence pointing it as the commit to
fix for backporting purposes, even if this commit is not introducing
any bug.

We regularly have new NAND controller drivers that are making use of
fields/hooks that we want to get rid of but can't because of all the
legacy drivers that we might break if we do.
So, instead of removing those fields/hooks, let's move them to a
sub-struct which is clearly documented as deprecated.
We start with the ->IO_ADDR_{R,W] fields.
