soc/amd/cezanne/fsp_m_params: set HD Audio enable UPD from devicetree
Pass the info if the non-graphics HD audio controller device is enabled
or disabled in the board's devicetree via a UPD to the FSP so that it
knows if it should enable or disable the corresponding device.
TEST=When adding "device ref hda on end" to the devicetree of
amd/majolica the non-graphics HD Audio controller shows up in lspci and
when that line isn't added the PCIe device doesn't show up.
