cx18: Prevent CX23418 from clearing it's outgoing ack interrupts to driver
From: Andy Walls <awalls@radix.net>
When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it
also received that interrupt and cleared the flag before the linux driver could
see what the interrupt was for. This fix prevents the CPU from receiving an
IRQ for it's own outgoing ack's to the linux driver. This fix is critical now
that the linux driver doesn't poll but relies on these ack interrupts.
Priority: high
