power: supply: mt6370: uses IIO interfaces, depends on IIO

The mt6370-charger driver uses IIO interfaces and produces build
errors when CONFIG_IIO is not set, so it should depend on IIO.

ERROR: modpost: "iio_read_channel_processed" [drivers/power/supply/mt6370-charger.ko] undefined!
ERROR: modpost: "devm_iio_channel_get_all" [drivers/power/supply/mt6370-charger.ko] undefined!
