[PATCH v2 12/12] ARM: dts: imx6sx: Use undeprecated reset-gpios and drop reset-gpio-active-high

[Krzysztof Kozlowski]

Freescale i.MX6 PCIe host controller bindings, through referenced
snps,dw-pcie-common.yaml schema, already document "reset-gpios", just
like Linux kernel did for a long time.  Use the preferred form over
"reset-gpio" which is deprecated since commit 42694f9f6407
("dt-bindings: PCI: add snps,dw-pcie.yaml") in 2021.

Linux kernel already properly parses GPIO active level from phandle
arguments, thus we can also drop "reset-gpio-active-high".

However this change will impact U-Boot, because it only parses
"reset-gpio" property for imx6q amd imx6sq.  Intention is to update
U-Boot to work with newer DTS, but any other out of tree user of this
DTS which did not implement undeprecated "reset-gpios" will be affected
as well.  There was plenty of time for these projects to switch to
undeprecated "reset-gpios", though.
