Use PCI device IDs from pci_ids.h header. BSW replaces CHV, as 0x22a8
was added in PCI header as BSW ID for consistency, as they are same
(similar) platforms. The ACPI IDs are used only internally and lower
16 bits uniquely define the device as vendor ID for Intel is 8086 for
all of them. Use PCI_DEVICE_DATA() to match PCI device to be consistent
with other Intel audio drivers.
