Pali Rohár 84ce1a8e36 mtd: rawnand: fsl_elbc: Fix none ECC mode 
[ Upstream commit 049e43b9fd ]

Commit f6424c22aa ("mtd: rawnand: fsl_elbc: Make SW ECC work") added
support for specifying ECC mode via DTS and skipping autodetection.

But it broke explicit specification of HW ECC mode in DTS as correct
settings for HW ECC mode are applied only when NONE mode or nothing was
specified in DTS file.

Also it started aliasing NONE mode to be same as when ECC mode was not
specified and disallowed usage of ON_DIE mode.

Fix all these issues. Use autodetection of ECC mode only in case when mode
was really not specified in DTS file by checking that ecc value is invalid.
Set HW ECC settings either when HW ECC was specified in DTS or it was
autodetected. And do not fail when ON_DIE mode is set.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
