Subject[PATCH] iio:dummy: Fix coding style in Kconfig
This patch fixes the checkpatch.pl warning:

drivers/iio/dummy/Kconfig:21: WARNING: please write a paragraph that
describes the config symbol fully
drivers/iio/dummy/Kconfig:29: WARNING: please write a paragraph that
describes the config symbol fully

This patch expands the explanation about IIO_DUMMY_EVGEN by using the
code documentation found in iio/dummy/iio_dummy_evgen.c. In the same
way, the information related to IIO_SIMPLE_DUMMY_BUFFER was extracted
from file iio_simple_dummy_buffer.c. Finally, this patch apply the
coding-style for Kconfig files (Documentation/process/coding-style.rst)
