[PATCH v2 20/20] iio: Remove support for the legacy event config interface

[Lars-Peter Clausen <lars@metafoo.de>]

Now that all drivers have been converted to the new event config interface we
can remove for the legacy event config interface. Also drop the '_new' suffix
for the event config interface callbacks, since those are the only callbacks
now.

Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
---
Only included for completeness, can be applied later.
