Intel introduced a new UPD specifically for setting the HDA subsystem ID
in FSP-M. Using SiSsidTablePtr in FSP-S no longer works as it will be
locked with a default value of 0 by that point.
Tested on Clevo V560TU with MTL FSP 4122.12 (0D.00.A8.20).
TEST=PCI config space for HDA device has subsystem ID set.
