Add new omit-battery-class property for bq256xxx for avoid creating
a battery device when a fuel gauge make one.

In my case i have a Redmi Note 5A with bq25601 charger and bq27426 fg
and two battery device is created one for the charger and one for the fg
It seems battery device created by fg would be enough.

This does not help much, basically repeats commit subject. You need to
answer to "why?".

You described the desired Linux feature or behavior, not the actual
hardware. The bindings are about the latter, so instead you need to
rephrase the property and its description to match actual hardware
capabilities/features/configuration etc.
