The dependency was clearly needed, without it it is possible to
build the core i2c driver as a loadable module and the bq27xxx
driver built-in, which results in link errors:

Nothing enabled by BATTERY_BQ27XXX depends on I2C, this workaround is not
correct as it prevents BATTERY_BQ27XXX from being built-in when I2C is a
module, there is no reason for this limitation.
The undefined references are caused by BATTERY_BQ27XXX being built-in AND
its I2C functionality being enabled (BATTERY_BQ27XXX_I2C) while I2C is a
module. Reorganizing this driver is being discussed anyway, but in the
meantime a more correct fix would be along the lines of:

That works too, there is just very little difference in the end here,
and it's easier to revert an patch that only introduces a regression
than to do a different hack, especially if it's going to be reworked
soon anyway.
Do you want to submit the above as a fixup to your other patch or
should we just do the revert? It would be good to get one of the two
into -rc1.

I can just submit this fix, it would probably be better for the short term
until the rework is done.
