Without the I2C driver, we get a few warnings:
drivers/power/bq27xxx_battery.c:288:12: error: 'bq27xxx_regs' defined but not used [-Werror=unused-variable]
static u8 *bq27xxx_regs[] = {
^
drivers/power/bq27xxx_battery.c:994:12: error: 'bq27xxx_powersupply_init' defined but not used [-Werror=unused-function]
static int bq27xxx_powersupply_init(struct bq27xxx_device_info *di,

drivers/power/bq27xxx_battery.c:1029:13: error: 'bq27xxx_powersupply_unregister' defined but not used [-Werror=unused-function]
static void bq27xxx_powersupply_unregister(struct bq27xxx_device_info *di)

In mainline kernels, this was addressed by a larger rework in 703df6c09795 ("power:
bq27xxx_battery: Reorganize I2C into a module"). We probably don't want this backported
into stable kernels, so instead let's shut up the warnings by marking the symbols
as __maybe_unused.
