Wei Yongjun 94588c1bf1 iio: dummy: Fix build error when CONFIG_IIO_TRIGGERED_BUFFER is not set
Gcc reports build error when CONFIG_IIO_TRIGGERED_BUFFER is not set:

riscv64-linux-gnu-ld: drivers/iio/dummy/iio_simple_dummy_buffer.o: in function `iio_simple_dummy_configure_buffer':
iio_simple_dummy_buffer.c:(.text+0x2b0): undefined reference to `iio_triggered_buffer_setup_ext'
riscv64-linux-gnu-ld: drivers/iio/dummy/iio_simple_dummy_buffer.o: in function `.L0 ':
iio_simple_dummy_buffer.c:(.text+0x2fc): undefined reference to `iio_triggered_buffer_cleanup'

Fix it by select IIO_TRIGGERED_BUFFER for config IIO_SIMPLE_DUMMY_BUFFER.

Fixes: 738f6ba118 ("iio: dummy: iio_simple_dummy_buffer: use triggered buffer core calls")

Industrial I/O subsystem Dummy Driver configuration

menu "IIO dummy driver" depends on IIO

config IIO_DUMMY_EVGEN select IRQ_SIM tristate

config IIO_SIMPLE_DUMMY tristate "An example driver with no hardware requirements" depends on IIO_SW_DEVICE help Driver intended mainly as documentation for how to write a driver. May also be useful for testing userspace code without hardware.

if IIO_SIMPLE_DUMMY

config IIO_SIMPLE_DUMMY_EVENTS bool "Event generation support" select IIO_DUMMY_EVGEN help Add some dummy events to the simple dummy driver.

  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.

config IIO_SIMPLE_DUMMY_BUFFER bool "Buffered capture support" select IIO_BUFFER select IIO_TRIGGER select IIO_KFIFO_BUF select IIO_TRIGGERED_BUFFER help Add buffered data capture to the simple dummy driver.

  Buffer handling elements of industrial I/O reference driver.
  Uses the kfifo buffer.
