[PATCH] iio: adc: select buffer for at91-sama5d2_adc

We need to select the buffer code, otherwise we get build errors
with undefined functions on the trigger and buffer,
if we select just IIO and then AT91_SAMA5D2_ADC from menuconfig

This adds a Kconfig 'select' statement like other ADC
drivers have it already.

Hello Jonathan,

While you are at it, I also found this small kconfig issue during my tests.
Would be good to have as a fix as well.

Thanks,
Eugen
