dt-bindings: mfd: ti,bq25703a: Expand to include BQ25792

TI BQ25792 is similar in operation to BQ25703A, but has a different
register layout and different current/voltage capabilities.

Expand the existing BQ25703A binding to include BQ25792, and move the
voltage and current limits into per-variant conditional statements.
