The MediaTek MT6370 is a highly-integrated smart power management IC,
which includes a single cell Li-Ion/Li-Polymer switching battery
charger, a USB Type-C & Power Delivery (PD) controller, dual Flash
LED current sources, a RGB LED driver, a backlight WLED driver,
a display bias driver and a general LDO for portable devices.

Add support for the MT6370 Flash LED driver. Flash LED in MT6370
has 2 channels and support torch/strobe mode.

This dependency makes no sense, as the options in the Kconfig you're putting
this into gets parsed only `if LEDS_CLASS_FLASH`.
Please remove that.

Well, if it depends on that being either y, m or n, it means that it does
not depend on that at all. Remove.
