This PR adds tacd and linux kernel support for industrial i/o (iio) buffering of the ADC on the LXA TAC powerboard.
The ADC is attached via SPI and always samples on its own in the background.

[x] A future libiio pull request that includes the workaround that is required to enable the iio buffer. This issue was already fixed in analogdevicesinc/libiio#744. I've backported the patch for now. The patch can be dropped on the next libiio update (which is already in meta-oe master).
