[PATCH v12.2 0/5] bq27xxx_battery partial series

Changes in this rev:

Removed macro for if (...) dev_dbg(...) from I/O helper functions.

Moved update_dm_block() to patch "Add power_supply_battery_info support".
No more refactoring please; it's not really improving the code itself :-)

set_cfgupdate is required for DM write on certain chips, see this Q&A
https://e2e.ti.com/support/power_management/battery_management/f/180/p/577798/2121489#2121489

Renamed dm_buf .full => .has_data, .updt => .dirty
dm_buf has 3 states: !has_data, has_data && !dirty, has_data && dirty
I considered a single field and enum values, but I think this is clearer.

Renamed set_cfgupdate(..., u16 flag => state)
We call set_cfgupdate(di, BQ27XXX_FLAG_CFGUP or 0)
We !!state to print the intended flag state in error msg.
