Alexandru Ardelean f3c034f617 iio: at91-sama5d2_adc: adjust iio_triggered_buffer_{predisable,postenable} positions 
The iio_triggered_buffer_{predisable,postenable} functions attach/detach
poll functions.

In most cases the iio_triggered_buffer_postenable() should be called first
to attach the poll function, and then the driver can init the data to be
triggered.
In this case it's the other way around: the DMA code should be initialized
before the attaching the poll function and the reverse should be done when
un-initializing.

To make things easier when removing the iio_triggered_buffer_postenable() &
iio_triggered_buffer_predisable() functions from the IIO core API, the DMA
code has been moved into preenable() for init, and postdisable() for
uninit.
