iio: Move IIO Dummy Driver out of staging This patch moves the reference IIO dummy driver from drivers/staging/iio into a separate folder, drivers/iio/dummy and adds the proper Kconfig and Makefile for it. A new config menu entry called IIO dummy driver has also been added in the Industrial I/O support menu, corresponding to this driver.

staging: iio: select IRQ_WORK for IIO_DUMMY_EVGEN The iio dummy code was recently changed to use irq_work_queue, but that code is compiled into the kernel only if IRQ_WORK is set, so we can get a link error here: drivers/built-in.o: In function `iio_evgen_poke': (.text+0x208a04): undefined reference to `irq_work_queue' This changes the Kconfig file to match what other drivers do.

The purpose of this is to generate 'fake' event interrupts thus
allowing that driver's code to be as close as possible to that
a normal driver talking to hardware.
