iio: adc: ad_sigma_delta: Select IIO_BUFFER_DMAENGINE and SPI_OFFLOAD
CONFIG_AD_SIGMA_DELTA uses several symbols that it does not explicitly
select. If no other enabled driver selects them, the build fails with
either a linker failure if the driver is built in or a modpost failure
if the driver is a module.
ld.lld: error: undefined symbol: devm_spi_offload_rx_stream_request_dma_chan
ld.lld: error: undefined symbol: devm_iio_dmaengine_buffer_setup_with_handle
ld.lld: error: undefined symbol: devm_spi_offload_trigger_get
ld.lld: error: undefined symbol: devm_spi_offload_get
ld.lld: error: undefined symbol: spi_offload_trigger_enable
ld.lld: error: undefined symbol: spi_offload_trigger_disable
Select the necessary Kconfig symbols to include these functions in the
build to clear up the errors.
