PM / devfreq: Fix incorrect type issue.

commit 5f25f066f75a67835abb5e400471a27abd09395b upstream.

time_in_state in struct devfreq is defined as unsigned long, so
devm_kzalloc should use sizeof(unsigned long) as argument instead
of sizeof(unsigned int), otherwise it will cause unexpected result
in 64bit system.
