Subject: [RFC 4/5] power: supply: bq27xxx: Add dev helper variable to bq27xxx_battery_i2c_probe()

Add a dev local variable to the bq27xxx_battery_i2c_probe(), to replace
"&client->dev" in various places.

Note the resulting cleanup is somewhat minimal, this is mostly
a preparation for adding ACPI enumeration support which will
use the new "dev" variable more.
