soc/intel/common: Fix ACPI device name for USB4 DMA device 

The USB4 host interface (DMA) devices need to use SA_DEVFN_*
instead of SA_DEV_* when determining the ACPI name.

The matching names are removed from the SOC-level ACPI name
handler since they are provided by this driver now.

TEST=boot on volteer and ensure TDM0 device is in the SSDT.
