mfd: Still check other interrupts if we get a wm831x touchscreen IRQ
It is possible that we will see another interrupt triggering at the same time as the touchscreen interrupts so it's still worth checking other possible sources. Almost all of the win from the fast path comes from only needing to read the primary register and saving the I/O costs.
