[PATCH] cpufreq: powernow-k8: Fix checkpatch warnings

[Stratos Karafotis <stratosk@semaphore.gr>]

Fix the following checkpatch warnings:

- WARNING: Prefer pr_err(... to printk(KERN_ERR ...
- WARNING: Prefer pr_info(... to printk(KERN_INFO ...
- WARNING: Prefer pr_warn(... to printk(KERN_WARNING ...
- WARNING: quoted string split across lines
- WARNING: line over 80 characters
- WARNING: please, no spaces at the start of a line

Also, define the pr_fmt macro instead of PFX for the module name.

Signed-off-by: Stratos Karafotis <stratosk@semaphore.gr>
