PM / devfreq: imx8m-ddrc: Remove imx8m_ddrc_get_dev_status
Current driver actually does not support simple ondemand governor as it's unable to provide device load information. So removing the unnecessary callback to avoid confusing. Right now the driver is using userspace governor by default. polling_ms was also dropped as it's not needed for non-ondemand governor.
