All the cases, were the DSDT IRQ settings should be used instead of the MADT override, are for IRQ 1 (the PS/2 kbd IRQ).
Simplify things by always honering the override for GSI != 1 (for non DMI quirked cases).
This allows removing the DMI quirks to honor the override for some non IRQ 1 IRQs on some AMD ZEN based Lenovo models.

I don't think this will work for the Lenovo ThinkPad neo 14 because according to https://bugzilla.kernel.org/show_bug.cgi?id=217731 it needs the override to also be skipped for IRQ 12.
You are right, thank you for catching this. I'll submit a v3 of the series with the check changed to:
if (gsi != 1 && gsi != 12) return true;
I'll update the Link: tags in the revert to add more bugreports Links including the 217731 bugzilla.
