For gpiod conversions, if we are not willing to chase whether existing
DTSes specify polarities
properly and create workarounds in case they are wrong, we should use
gpiod_set_raw_value*()
(my preference would be to do the work and not use "raw" variants).

In this particular case, arch/arm/boot/dts/vf610-zii-dev-rev-c.dts
defines reset line as active low,
so you are leaving the device in reset state.

Please review your other conversion patches.
