[PATCH] char: tpm: Use SIMPLE_DEV_PM_OPS for ibmvtpm power management

Replace the manually defined dev_pm_ops structure with the
SIMPLE_DEV_PM_OPS macro to simplify the power management code.
This macro automatically handles CONFIG_PM_SLEEP configuration,
generating the same suspend/resume callbacks while reducing
boilerplate code.Add the value of 'thaw,freeze,poweroff,restore'.
