Revert "genirq: Use irqd_get_trigger_type to compare the trigger type for shared IRQs"

This reverts commit 9d0273bb which is
commit 382bd4de61827dbaaf5fb4fb7b1f4be4a86505e7 upstream.

It causes too many problems with the stable tree, and would require too
many other things to be backported, so just revert it.
