Make the tpm_i2c_infineon driver define its PM callbacks trough a
struct dev_pm_ops by using SIMPLE_DEV_PM_OPS instead of coding it
explicitly.
This simplifies the code and allows the driver to use tpm_pm_suspend()
and tpm_pm_resume() as its PM callbacks directly, without defining its
own PM callback routines.

Thanks Kent and Rafael - much better this way ;)
