tpm_atmel: Use struct dev_pm_ops for power management
Make the tpm_atmel driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct platform_driver. This allows the driver to use tpm_pm_suspend() and tpm_pm_resume() as its PM callbacks directly, without defining its own PM callback routines. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
