[nb|sb]/amd/[amdfam10|sb700]: Add LPC bridge ACPI names for NB/SB
Adds the necessary plumbing for acpi_device_path() to find the LPC bridge on the AMD Family10h/15h northbridges and SB700 southbridge. This is necessary for TPM support since the acpi path to the LPC bridge doesn't match the built-in default in tpm.c This is a port of GIT hash d8a2c1fb by Tobias Diedrich.
