Add properties ti,cfg-dac-minus-one-milli-percent and
ti,cfg-dac-plus-one-milli-percent to support voltage tuning
of logical levels -1/+1 of the MLT-3 encoded TX data.

Changes in v2:
- squash the 2 DT bindings patches in one single patch
- drop redundant "binding" from the DT bindings patch title
- rename DT properties and define them as percentage
- add default value for each new DT property
