Overview:
* Reorganizes chip data definitions
* Enables features landed in these patches:
  dt-bindings: power: supply: bq27xxx: Add monitored-battery documentation
  power: supply: bq27xxx: Add chip data memory read/write support
  power: supply: bq27xxx: Add power_supply_battery_info support
* Supports the following chips (only BQ27425 is active)
  BQ27500, 545, 425, 421, 441, 621

Changes in v3:
* BQ27425 tested; workaround minor chip bug
* Dropped driver_version
* Fixed dbg_dupes logic for .props & .dm_regs
* Dropped two props array dupes

Changes in v2:
* Added di->opts flags for remaining chip features
* Commented out untested bq27xxx_dm_regs parameters
* Changed dbg_dupes to run only once

Notes on v1:
* Not fully tested (hence RFC tag)
Thanks, full series queued.

Anyway, I've not got the time to fight these changes anymore, but at
very least could you drop 4/5, it's static analysis code made into a
runtime check built into a kernel driver, if not at least add my
nacked-by. :)
Since it's not critical at all and nobody depends on it, I dropped 4/5
for now. I agree, that checking it at runtime is not nice. On the other
hand I do think a duplication check makes sense. Doing a static
check should be possible, but I have no idea how to implement this
(without much effort). I suspect Coccinelle can do it, so I added
Julia.

For reference this is the runtime check:
