Chuanhong Guo 712302aed1 mtd: rawnand: fix ecc parameters for mt7622
[ Upstream commit 9fe4e0d3cb ]

According to the datasheet, mt7622 only has 5 ECC capabilities instead
of 7, and the decoding error register is arranged  as follows:
+------+---------+---------+---------+---------+
| Bits |  19:15  |  14:10  |   9:5   |   4:0   |
+------+---------+---------+---------+---------+
| Name | ERRNUM3 | ERRNUM2 | ERRNUM1 | ERRNUM0 |
+------+---------+---------+---------+---------+
This means err_mask should be 0x1f instead of 0x3f and the number of
bits shifted in mtk_ecc_get_stats should be 5 instead of 8.

This commit introduces err_shift for the difference in this register
and fix other existing parameters.

Public MT7622 reference manual can be found on [0] and the info this
commit is based on is from page 656 and page 660.

README

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.
