soc/intel/mtl: Set HDA subsystem ID during FSP-M

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. Change-Id: I5e668747d99b955b0a3946524c5918d328b8e1d3 Signed-off-by: Tim Crawford <tcrawford@system76.com>
