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 with bq27z746 I looked at some of the technical
reference manuals for the other bq27xxx devices, and noticed some
discrepancies with the driver. Fix these issues while we are at it.

For reference the TRMs for the affected bq chips can be found at these
direct links:
