Yes, I can confirm, SSP1 in under LPEA

    Scope (_SB)
    {
        Device (LPEA)
        {
            Name (_ADR, Zero)  // _ADR: Address
            Name (_HID, "80860F28" /* Intel SST Audio DSP */)  // _HID: Hardware ID

            ... snip ...

            Device (SSP1)
            {
                Name (_ADR, Zero)  // _ADR: Address
                Name (_HID, "SSPX0000" /* Intel SSP Device */)  // _HID: Hardware ID
                Name (_CID, "SSPX0000" /* Intel SSP Device */)  // _CID: Compatible ID
