media: i2c: imx412: Fix reset GPIO polarity

commit bb25f071fc92d3d227178a45853347c7b3b45a6b upstream.

The imx412/imx577 sensor has a reset line that is active low not active
high. Currently the logic for this is inverted.

The right way to define the reset line is to declare it active low in the
DTS and invert the logic currently contained in the driver.

The DTS should represent the hardware does i.e. reset is active low.
So:
+               reset-gpios = <&tlmm 78 GPIO_ACTIVE_LOW>;
not:
-               reset-gpios = <&tlmm 78 GPIO_ACTIVE_HIGH>;

I was a bit reticent about changing this logic since I thought it might
negatively impact @intel.com users. Googling a bit though I believe this
sensor is used on "Keem Bay" which is clearly a DTS based system and is not
upstream yet.
