Subject: [PATCH v2 2/2] arm64: dts: qcom: sm6125: Add GPI DMA nodes

From: Martin Botka <martin.botka@...ainline.org>

Add nodes for GPI DMA hosts on SM6125.

Signed-off-by: Martin Botka <martin.botka@...ainline.org>
[Marijn: reorder properties, use sdm845 fallback compatible, disable by
 default, use 3 instead of 5 dma cells]
