Binbin Zhou dbbc17735a gpio: loongson: Fix Loongson-2K2000 ACPI GPIO register offset 
commit e59f4c9717 upstream.

Since commit 3feb70a617 ("gpio: loongson: add more gpio chip
support"), the Loongson-2K2000 GPIO is supported.

However, according to the firmware development specification, the
Loongson-2K2000 ACPI GPIO register offsets in the driver do not match
the register base addresses in the firmware, resulting in the registers
not being accessed properly.

Now, we fix it to ensure the GPIO function works properly.

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.
