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.

iio: dummy: Add correct tabs and spaces to Kconfig

Kconfig from iio/dummy does not follow the coding style recommendations.
According to the coding-style, Lines under a config definition are
