SubjectRe: [PATCH v3 2/8] wlcore: set irq_flags in the board files instead of hiding behind a quirk

BTW, there seems to be a patch on its way to make reading the flags
easier (ie. no need to get the irq_data first):

http://mid.gmane.org/1367945288-5625-1-git-send-email-javier@dowhile0.org

I'm not sure if this is going to be taken in, but if it does, it would
be nice to change the code here to use the new irq_get_trigger_type()
function.
