mfd: Add fast path for WM831x touchscreen interrupts
The WM831x interrupt controller provides reporting of the touchscreen related interrupts in the primary interrupt status register as a performance optimisation - use this to avoid reading the secondary status registers for those interrupts. For code simplicity and to avoid iterating over all interrupts we open code for the two affected interrupt sources.
