The LPSS driver prepares for enumeration only single devices, such as DMA, UART, SPI, I²C. Hence the registration of AudioDSP should not be covered. Moreover, the very same ACPI _HID has been added by the catpt driver a few years ago. And even more serious issue with this, is that the register window at offset 0x800 is actually D-SRAM0 in case of AudioDSP and writing to it is a data corruption. That all being said, remove the AudioDSP ID from the LPSS driver, where it doesn't belong to.
