Add Legacy PM OPS usage checks to __class_register() function. If Legacy PM OPS
usage is found, print warning message to indicate the driver code needs
updating to use Dev PM OPS interfaces. This will help serve as a way to track
drivers that still use Legacy PM OPS and fix them.
The Legacy PM OPS check looks for suspend(struct device *, pm_message_t) or
resume(struct device *) class level interfaces.
