arm64: dts: imx8-apalis: set correct gpios for hsio clocks
Set the correct gpios for the hsio clocks. This will allow us to use the
predefined hsio clocks from NXP to enable the pcie and sata clocks.
Upstream-Status: Pending
Mainline for i.MX 8 does not support PCIe yet, this patch cannot be
upstreamed as of now.
