cpufreq: ppc-corenet-cpufreq: Fix __udivdi3 modpost error
bfa709bc823fc32ee8dd5220d1711b46078235d8 (cpufreq: powerpc: add cpufreq
transition latency for FSL e500mc SoCs) introduced a modpost error:
ERROR: "__udivdi3" [drivers/cpufreq/ppc-corenet-cpufreq.ko] undefined!
make[1]: *** [__modpost] Error 1
Fix this by avoiding 64 bit integer division.
gcc version 4.8.2
Fixes: bfa709bc823f (cpufreq: powerpc: add cpufreq transition latency for FSL e500mc SoCs)
