Hi Marek,

The MIC2025 switch input signal nEN is active low, describe it as such
in the DT. The previous change to this regulator polarity was incorrectly
influenced by broken quirks in gpiolib-of.c, which is now long fixed. So
fix this regulator polarity setting here once and for all.

Don't you mean: gpio = <&gpio1 2 GPIO_ACTIVE_LOW> here?
