ACPI: LPSS: Remove AudioDSP related ID
The AudioDSP drivers are in control for all functions of the hardware
they have (they are multi-functional devices). 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.
