[RFC PATCH 1/5] iio: core: initialize 'modes' to INDIO_DIRECT_MODE by default

[Alexandru Ardelean]

Most of the IIO drivers initialize to INDIO_DIRECT_MODE mode. Some
initialize to INDIO_BUFFER_SOFTWARE as a way to create an IIO device that
is just mostly an IIO buffer.

All IIO devices initialize the 'modes' parameter. Since this is
overwritten, might as well make INDIO_DIRECT_MODE the default. This would
not affect any current IIO driver.

Then for the IIO devices that only have direct-mode, this initialization
can be removed, since it becomes boiler-plate code.
