drivers/rtc/class: convert from Legacy pm ops to dev_pm_ops

Convert drivers/rtc/class to use dev_pm_ops for power management and
remove Legacy PM ops hooks.  With this change, rtc class registers
suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy
class->suspend/resume.  When __device_suspend() runs call-backs, it will
find class->pm ops for the rtc class.
