iio: adc: ad7192: Silence no spi_device_id warnings

SPI devices use the spi_device_id for module autoloading even on
systems using device tree, after commit 5fa6863ba692 ("spi: Check
we have a spi_device_id for each DT compatible"), kernel warns as
follows since the spi_device_id is missing:

SPI driver ad7192 has no spi_device_id for adi,ad7190
SPI driver ad7192 has no spi_device_id for adi,ad7193
SPI driver ad7192 has no spi_device_id for adi,ad7195

Add spi_device_id entries to silence the warnings, and ensure driver
module autoloading works.
