iio: health/afe440x: Remove channel names
These AFEs have 4 ADC mesuring stages (called LED2, ALED2, LED1, and ALED1 in the datasheet), we map these as channels, these stages can serve different purposes depending on the application. For instance the AFE4404 has an additional LED (LED3), this LED can be timed to be active during stage 2 (or anystage, but the datasheet describes this case and the name of the stage reflects this use). This ability is used further in upcoming parts that tie the front-end gain and the LED timings together. For these reasons we remove explicit naming the channels. Without channel names it is best that the index numbers are in order to match the stage number, reorder the channel numbers. Signed-off-by: Andrew F.
