southbridge/amd: Add LPC bridge acpi path for Family14 and SB800
Adds the necessary plumbing for acpi_device_path() to find the LPC
bridge on the AMD Family14 northbridge with an SB800 southbridge.
This is necessary for TPM support since the acpi path to the LPC bridge
(_SB.PCI0.ISAB) doesn't match the built-in default in tpm.c
(_SB.PCI0.LPCB).
