slight prettying of acpicpu output

[John L. Scarfone]

This changes the dmesg on one acpi enabled machine:

 acpiprt3 at acpi0: bus -1 (MPCI)
-acpicpu0 at acpi0acpicpu0: struck PSS entry, core frequency equals  last
-acpicpu0: struck PSS entry, core frequency equals  last
+acpicpu0 at acpi0
+acpicpu0: struck PSS entry, core frequency equals last
+acpicpu0: struck PSS entry, core frequency equals last
 acpicpu0: invalid _PSS length
-: C2
+acpicpu0: C2
 acpipwrres0 at acpi0: PADA
