This series introduces the correct usage of user data length for
H6/H616.
If the older SoCs must use a fixed value of 4 user data bytes for each
ECC step, the H6 can have a different value for each step.

In the first round, the behavior was kept as the one used by A10 when in
fact the images in the wild with the vendor kernel are using a different
layout.

The first patches are fixes/code cleaning and the last one enables using
a variable user data length for H6/H616

Changes from v1:
- gather Reviewed-by/Acked-by
- rework patch 1 subject (more a code clarification than a fix)
- fix typo in patch 2
- remove patch 4 Fixes since it's not really a fix
