Liam Breck 05045379b2 power: supply: bq27xxx: Enable data memory update for certain chips
Support data memory update on BQ27425. Parameters from TI datasheets are also
provided for BQ27500, 545, 421, 441, 621; however these are commented out,
as they are not tested.

Add BQ27XXX_O_CFGUP & _O_RAM for use in bq27xxx_chip_data[n].opts
and by data memory update functions.
