PM / sleep: add TEST_PLATFORM support for freeze state
Invoke freeze_enter() after suspend_test(TEST_PLATFORM) being invoked. So when setting /sys/power/pm_test to "platform", it can be used to check if freeze state is working well after all devices are suspended and before processors are blocked, Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Rafael J.
