iio: adc: ad7476: Use correct channel for bit info
The ad7476 supports ADCs which use separate GPIO for starting the
conversion. For such devices, the driver uses different channel
information if the GPIO is found. The bit information is still always
used from the original (non 'convstart') channels.
This has not been causing problems because the bit information for the
'convstart' -channel and the 'normal' -channel is identical. It,
however, will cause issues if an IC has different characteristics for an
'convstart' -channel and regular channel. Furthermore, this will cause
problems if a device always requires the convstart GPIO and thus only
defines the convstart channel.
