The wait instruction encoding changed between ISA v2.07 and ISA v3.0. In v3.1 the instruction gained a new field. Update the PPC_WAIT macro to the current encoding. Rename the older incompatible one with a _v203 suffix as it was introduced in v2.03 (the WC field was introduced in v2.07 but the kernel only uses WC=0).

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.
