iio: accel: adxl380: reject devices without match data
SPI driver_override allows a device to bind to this driver without
matching either the OF or SPI device ID table. In that case,
spi_get_device_match_data() returns NULL.
adxl380_spi_probe() passes the result to adxl380_probe(), which
dereferences chip_info to set the IIO device name and operations,
causing a NULL pointer dereference.
Commit 572a00852635 ("iio: dac: ad5686: missing NULL check on match
data") fixed the same driver_override issue in another SPI driver.
Reject devices without match data in the SPI frontend.
