Commitffd381445e("serial: 8250: dw: Move the USR register to pdata") caused NULL-pointer dereference when booting with ACPI by unconditional usage of the recently added pdata. In order to fix that and prevent similar issues in future, hook the default version of this structure in dw8250_acpi_match table. While at it, sort all entries alphabetically.

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.
