2019-07-27iio: move 3-wire spi initialization to st_sensors_spiDenis Ciocca1-2/+2
Some devices need to be configured with special bit in order to use spi 3-wire. This was done during device identification phase. Instead, let's move this part as spi specific. Doing this the check_device_support function becomes a simple device id check, so let's rename it.
