iio: adc: ad7124: Remove input number limitation
The driver limits the user to use only 4/8 differential inputs, but this device has the option to use pseudo-differential channels. This will increase the number of channels to be equal with the number of inputs so 8 channels for ad7124-4 and 16 for ad7124-8. This patch removes the check between channel nodes and num_inputs value. Signed-off-by: Mircea Caprioru <mircea.caprioru@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
