[PATCH v2 3/3] iio: adc: twl4030-madc: add missing of.h include

[Dmitry Torokhov]

The driver is using of_device_id/of_match_ptr() and therefore needs
to include of.h header. We used to get this definition indirectly via
inclusion of matrix_keypad.h from twl.h, but we are cleaning up
matrix_keypad.h from unnecessary includes.
