soc/amd/picasso/acpi: Remove padding in IVRS table caused by realignment.
Previous CL (1916f8969b10e27fe06b3e0eb1caae632bd947f6) misinterpreted
spec as requiring size alignment on all IVHD device entries. The correct
requirement specifies only for 4-byte entries. The unneeded realignments
result in gaps in the table. The kernel hangs in early boot due to the
malformed table.
Remove 8-byte entry alignment.
BUG=b:166519072
TEST=Boot fully to morphius board with and without amd_iommu kernel
parameter. Confirm IVRS contains no alignment gaps/corruption.
