ASoC: SOF: ipc4-topology: support NHLT device type

The endpoint in NHLT table for a SSP port could have the device type NHLT_DEVICE_BT or NHLT_DEVICE_I2S. Use intel_nhlt_ssp_device_type() function to retrieve the device type before querying the endpoint blob to make sure we are always using correct device type parameter.
