By optionally putting the pins into sleep state in the .runtime_suspend callback we can accomplish two things. One is to minimize current leakage from pins and thus save power, second we can prevent the IP from driving pins output in an uncontrolled manner, which may happen if the power domain drops the domain regulator. When returning from idle, entering .runtime_resume callback, the pins are restored to default state.
