4.16-stable review patch. If anyone has any objections, please let me know.

From: Eugen Hristev eugen.hristev@microchip.com
commit 76974ef9d1bf397b7bb97892a3b3bc516a1fc2c2 upstream.
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.
