Sean Nyekjaer bd844f8b87 iio: adc: stm32-adc: skip adc-diff-channels setup if none is present 
commit 9c0d6ccd7d upstream.

If no adc differential channels are defined driver will fail with EINVAL:
stm32-adc: probe of 48003000.adc:adc@0 failed with error -22

Fix this by skipping the initialization if no channels are defined.

This applies only to the legacy way of initializing adc channels.
