This implements buffered reads for the ad4695 driver using the typical
triggered buffer implementation, including adding a soft timestamp
channel.
The chip has 4 different modes for doing conversions. The driver is
using the advanced sequencer mode since that is the only mode that
allows individual configuration of all aspects each channel (e.g.
bipolar config currently and oversampling to be added in the future).

If we're returning because "reg >= HX9023S_CH_NUM" then set the error code
to -ENIVAL instead of success.

The current code is always iterating over two fields in the
noa1305_int_time_available array. Fix iteration limit, which
has to be halved to avoid out of bounds access in case the
value that is being looked up is not in the array.

Add support for ENS210/ENS210A/ENS211/ENS212/ENS213A/ENS215.
The ENS21x is a family of temperature and relative humidity sensors with
accuracies tailored to the needs of specific applications.
