cpufreq: s3c2412: use global s3c2412_cpufreq_setrefresh
There are two identical copies of the s3c2412_cpufreq_setrefresh
function: a static one in the cpufreq driver and a global
version in iotiming-s3c2412.c.
As the function requires the use of a hardcoded register address
from a header that we want to not be visible to drivers, just
move the existing global function and add a declaration in
one of the cpufreq header files.
