3.7-stable review patch. If anyone has any objections, please let me know.

commit cbbc0138efe1dcd5426b8fc5d87741f5057aee72 upstream.
We were using wrong IRQ number so clearing wasn't working at all. Depending on a platform this could result in a one device having two interrupts assigned. On BCM4706 this resulted in all IRQs being broken.
