Add a new multi-chan IP core (0x12) support which is used in Loongson- 2K3000/Loongson-3B6000M. Compared with the 0x10 core, the new 0x12 core reduces channel numbers from 8 to 4, but checksum is supported for all channels. Add a "multichan" flag to loongson_data, so that we can simply use a "if (ld->multichan)" condition rather than the complicated condition "if (ld->loongson_id == DWMAC_CORE_MULTICHAN_V1 || ld->loongson_id == DWMAC_CORE_MULTICHAN_V2)".

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 reStructuredText 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.
