PM / sleep: Fix entering suspend-to-IDLE if no freeze_oops is set
If no freeze_ops is set, trying to enter suspend-to-IDLE will cause a nice oops in platform_suspend_prepare_late(). Add respective checks to platform_suspend_prepare_late() and platform_resume_early() functions. Fixes: a8d46b9e4e48 (ACPI / sleep: Rework the handling of ACPI GPE wakeup ...)
