[PATCH 3/7] iio: adc: ad7091r: Move defines to header file

From: marcelo.schmitt
Date: Tue Nov 21 2023 - 16:35:57 EST


From: Marcelo Schmitt <marcelo.schmitt@xxxxxxxxxx>

Move AD7091R register, channel and event definitions to the header file
so other AD7091R device drivers may use those declaration in follow up
patches.

Signed-off-by: Marcelo Schmitt <marcelo.schmitt@xxxxxxxxxx>
