[PATCH] genirq: add IRQ_TYPE_SENSE_MASK
Add a #define for the mask of the part of IRQ_TYPE that represents the trigger type. I use that in my in-progress work as I've standardized the way the irq description in the firmware device-tree get translated to linux useable things by using those constants. Having this mask to isolate the "trigger type" part of the flags is useful in a few places.
