This change-set adds support for AD7607, AD7608 and AD7609.
These parts are simpler parts for the AD7606x family. They support only
HW-only mode like AD7605, but they support oversampling like the other
AD7606x parts.
AD7607 has a 14-bit resolution.
AD7608 and AD7609 are 18-bit resolution.
AD7607 & AD7608 supports +/-5V and +/-10V ranges.
AD7609 supports +/-10V & +/-20V ranges.
The oversampling settings are the same.
Because of AD7607, the scales had to be reworked (again), but this time
doing away with the allocation at runtime for the scale-available-show
values. This time, the full IIO_VAL_INT_PLUS_MICRO values are stored
statically. AD7607 supports a scale of 1.220703, which is the first and
only (so far) scale that is above 1.
This patchset contains a few small bug-fixes found during more testing of
these parts.
