Subject: [PATCH] fix incorrect initialization code for trans_stat of devfreq

Hi,

I met trans_stat abnormal issue while debugging devfreq feature for ddr in arm64 system, cat trans_stat 
would get extremely large time value which is unreasonable, I checked the code and found it was caused by
incorrect initialization code, time_in_state is initialized by devm_kzalloc and wrongly use sizeof(unsigned int)
as argument, but time_in_state which is defined in struct devfreq actually is defined as unsigned long, so
it is ok for 32 bit system, but will cause unexpected result in 64 bit system.

  PM / devfreq: Fix incorrect type issue.
