Users already found correct "ivrs_ioapic=" values, let's put them inside
kernel to workaround buggy BIOS.

Will that still work when a fixed BIOS for these laptops is released?

Do you mean that we should stop applying these quirks once a BIOS fix is confirmed?

We can modify the quirk to compare BIOS version, if there’s an unlikely BIOS update really fixes the issue.
Before that happens, I think it’s OK to let the quirks stay this way.
