Fix _OSC UUID in pcc-cpufreq

BugLink: http://bugs.launchpad.net/bugs/793702

commit 904cc1e637a00dba1b58e7752f485f90ebf2a568 upstream.

UUID needs to be written out the way it is described in
Sec 18.5.124 of ACPI 4.0a Specification.

Platform firmware's use of this UUID/_OSC is optional, which is
why we didn't notice this bug earlier.
