Subject: [PATCH 1/6] arm64: dts: qcom: msm8996: fix sound card reset line polarity

When resetting the block, the reset line is being driven low and then
high, which means that the line in DTS should be annotated as "active
low". It will become important when wcd9335 driver will be converted
to gpiod API that respects declared line polarities.
