Mark Brown 25a947f805 mfd: Convert Wolfson MFD drivers to use irq_data accessor function 
Actually makes the code larger rathe rthan smaller but does provide some
isolation against core API changes.

Mark Brown baa3f63b88 mfd: Convert WM8994 to new irq_ interrupt methods 
Kernel 2.6.37 adds new interrupt methods which take a struct irq_data
rather than an irq number. Convert over to these as they will become
mandatory in future.

Mark Brown c9fbf7e070 mfd: Add WM8994 interrupt controller support 
The WM8994 has an interrupt controller which supports interrupts for
both CODEC and GPIO portions of the chip. Support this using genirq,
while allowing for systems that do not have an interrupt hooked up.

Wrapper functions are provided for the IRQ request and free to simplify
the code in consumer drivers when handling cases where IRQs are not
set up.
