ASoC: SOF: amd: Propagate PCI subsystem Vendor and Device IDs

Extend the AMD SOF machine driver to propagate the PCI subsystem
Vendor and Device IDs so that they may be subsequently used as an
SSID. Store the subsystem IDs in acp_dev_data during probe (both
amd_sof_acp_probe and amd_sof_acp7x_probe), and propagate them
to mach_params in the SoundWire machine select path.
