Subject: [PATCH] iio: light: jsa1212: remove unneeded i2c check functionality
 test

This driver does not call i2c_smbus_read|write_byte_data(),
so remove the corresponding functionality test. It uses regmap
to handle byte transfers transparently.

Found & fixed by inspection based on same defect recently fixed
in light/tpl0102 driver.
