[CPUFREQ] powernow-k8 cleanup msg if BIOS does not export ACPI _PSS cpufreq data
- Make the message shorter and easier to grep for - Use printk_once instead of WARN_ONCE (functionality of these was mixed) Signed-off-by: Thomas Renninger <trenn@suse.de> Cc: Langsdorf, Mark <mark.langsdorf@amd.com> Signed-off-by: Dave Jones <davej@redhat.com>
