iio: adc: at91-sama5d2_adc: disable/prepare buffer on suspend/resume
In case triggered buffers are enabled while system is suspended they will
not work anymore after resume. For this call at91_adc_buffer_postdisable()
on suspend and at91_adc_buffer_prepare() on resume. On tests it has been
seen that at91_adc_buffer_postdisable() call is not necessary but it has
been kept because it also does the book keeping for DMA. On resume path
there is no need to call at91_adc_configure_touch() as it is embedded in
at91_adc_buffer_prepare().
Fixes: 073c662017f2f ("iio: adc: at91-sama5d2_adc: add support for DMA")
