staging:iio:lpc32xx_adc: Ensure request_irq and free_irq dev_id parameter match

The data parameters for request_irq and free_irq have to match, otherwise the
IRQ wont be freed.

The issue has been discovered using the following coccinelle patch:

// <smpl>
@r1@
type T;
T data;
@@
(
request_irq(..., (void *)data)
|
request_irq(..., data)
|
request_threaded_irq(..., (void *)data)
|
request_threaded_irq(..., data)
)

@r2@
type r1.T;
T data;
position p;
@@
(
free_irq@p(..., (void *)data)
|
free_irq@p(..., data)
)

@depends on r1@
position p != r2.p;
@@
*free_irq@p(...)

// </smpl>
