Precedence: bulk

To include kernel/Kconfig.freezer to make sure the dependency between
CONFIG_CGROUP_FREEZER and CONFIG_FREEZER

It will cause building error when I make allmodconfig.

kernel/cgroup/freezer.c: In function 'freezer_css_online':
kernel/cgroup/freezer.c:116:15: error: 'system_freezing_cnt' undeclared (first use in this function)
   atomic_inc(&system_freezing_cnt);
