 Log Message:
 hdaudio: pci: PCIe config space fixes and Intel PCH snoop support
 
 The HD audio specification does not cover PCI config space, and this
 driver was unconditionally writing to a vendor specific register. Reduce
 scope of config space accesses based on PCI IDs.
 
 With this cleaned up, add support for Intel PCH devices which require
 some additional vendor specific configuration to bypass no snoop mode.
