bq27z746 is similar to bq27z561 but with additional protection
functionality. The standard register set is identical, but the
extended registers accessed through AltManufacturerAccess has
differences.
While working on the series I also noticed that bq27z561 supports
interrupts, but the dt binding marks it as unsupported. Fix while at
it.
For reference the TRMs for the affected bq chips can be found at these
direct links:
