Subject: [PATCH -next] power: supply: mt6370: Fix Kconfig dependency

If CONFIG_IIO is not set,
make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-,
will be failed, like this:

drivers/power/supply/mt6370-charger.o: In function `mt6370_chg_mivr_dwork_func':
mt6370-charger.c:(.text+0x670): undefined reference to `iio_read_channel_processed'
drivers/power/supply/mt6370-charger.o: In function `mt6370_chg_probe':
mt6370-charger.c:(.text+0xb43): undefined reference to `devm_iio_channel_get_all'
make: *** [vmlinux] Error 1

To fix this build error, add depends on IIO to config CHARGER_MT6370 dependency.
