All devices using a triggered buffer need to attach and detach the trigger to the device in order to properly work. Instead of doing this in each and every driver by hand move this into the core. At this point in time, all drivers should have been resolved to attach/detach the poll-function in the same order. This patch removes all explicit calls of iio_triggered_buffer_postenable() & iio_triggered_buffer_predisable() in all drivers, since the core handles now the pollfunc attach/detach. The more peculiar change is for the 'at91-sama5d2_adc' driver, since it's not immediately obvious that removing the hooks doesn't break anything. Eugen was able to test on at91-sama5d2-adc driver, sama5d2-xplained board. All seems to be fine.
