Add devres helpers - devm_reset_control_bulk_get_exclusive_deasserted - devm_reset_control_bulk_get_optional_exclusive_deasserted - devm_reset_control_bulk_get_optional_shared_deasserted - devm_reset_control_bulk_get_shared_deasserted - devm_reset_control_get_exclusive_deasserted - devm_reset_control_get_optional_exclusive_deasserted - devm_reset_control_get_optional_shared_deasserted - devm_reset_control_get_shared_deasserted to request and immediately deassert reset controls. During cleanup, reset_control_assert() will be called automatically on the returned reset controls.
