This patch fixes the PIR routing setup using the current PIR table for Geode 5536 systems. I think that this is also the v3 db800 and other 5536 Linux booting problems.

Don't check exclusive IRQ field. This field is rarely used (and not used in
the LX tables). There is not a good reason to mask off non-exclusive IRQs.
