The R21 AMD IOMMU bypass rules in 65-iommu-amd.toml were missing
the flags line on each entry, so the AcpiQuirkFlags returned
by apply_dmi_acpi_quirk_rules was always empty and the iommu
daemon's check_dmi_ivrs_bypass() never triggered.
Add flags = ["suppress_ivrs"] to all 4 entries (Dell Inspiron
7375, Dell Latitude 5495, Acer Aspire A315-41, Lenovo IdeaPad
330S-15ARR) so the bypass logic actually fires on the matched
systems.
Without this fix, the iommu daemon would attempt to initialize
the broken AMD-Vi silicon and hang the boot on those specific
laptops — the very regression the R21 data file was meant to
prevent.
