iio: st-sensors: Update ST Sensor bindings
This adjusts the ST Sensor bindings with the more fine-grained syntax checks that were proposed late in the last kernel cycle and colliding with parallel work.

description: The STMicroelectronics sensor devices are pretty straight-forward

I2C or SPI devices, all sharing the same device tree descriptions no matter
|

what type of sensor it is.
|

Note that whilst this covers many STMicro MEMs sensors, some more complex
|

IMUs need their own bindings.
