Revert "power: bq27xxx_battery: Remove unneeded dependency in Kconfig"

This reverts commit 6bd03ce3c12a22d86f59070f1da15aaa2bde8a51, it was applied
in error and cuased this link failure

drivers/built-in.o: In function `bq27xxx_battery_i2c_read':
core.c:(.text+0xa6da8): undefined reference to `i2c_transfer'
drivers/built-in.o: In function `bq27xxx_battery_init':
core.c:(.init.text+0x68e0): undefined reference to `i2c_register_driver'
drivers/built-in.o: In function `bq27xxx_battery_exit':
core.c:(.exit.text+0xc6c): undefined reference to `i2c_del_driver'

Later upstream kernels fixed this with a larger rework in commit
703df6c09795 ("power: bq27xxx_battery: Reorganize I2C into a module"),
but we cannot backport that to 4.4.
