Make acpi_cpc_valid() check if ACPI is disabled, so that its callers don't need to check that separately. This will also cause the AMD pstate driver to refuse to load right away when ACPI is disabled. Also update the warning message in amd_pstate_init() to mention the ACPI disabled case for completeness.

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.
