Commit 202e683df37c ("cpufreq: amd-pstate: add amd-pstate driver
parameter for mode selection") changed the driver to be disabled by
default, and this can suprise users.
Let users know what happened so they can decide what to do next.

BugLink isn't an official tag, you should use "Link".

The file uses `pr_fmt` so this will show up as `amd_pstate: amd_state is
