pnpacpi: fix IRQ flag decoding
When decoding IRQ trigger mode and polarity, it is not enough to mask by
IORESOURCE_BITS because there are now additional bits defined. For
example, if IORESOURCE_IRQ_SHAREABLE was set, we failed to set *triggering
and *polarity at all.
I can't point to a failure that this patch fixes, but
bugs in this area have caused problems when resuming after
suspend, for example:

This is based on a patch by Tom Jaeger:
