iio: adc: ad7124: Silence no spi_device_id warnings

Browse Source 
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 ad7124 has no spi_device_id for adi,ad7124-4
SPI driver ad7124 has no spi_device_id for adi,ad7124-8

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