arm64: dts: qcom: sm8350: Fix DMA0 address

DMA0 node downstream is specified at 0x900000, so fix the typo. Without
this, enabling any i2c node using DMA0 causes a hang.

Fixes: bc08fbf49bc8 ("arm64: dts: qcom: sm8350: Define GPI DMA engines")
Fixes: 41d6bca799b3 ("arm64: dts: qcom: sm8350: correct DMA controller unit address")
