Be similar with commit (ata: Disabling the async PM for JMicron chip 363/361), Barto found the similar issue for JMicron chip 368, that 363/368 has no parent-children relationship, but they have the power dependency. So here we can exclude the JMicron chips out of pm_async method directly, to avoid further similar issues.
