dmaengine: qcom: gpi: set DMA_PRIVATE capability

Browse Source 
[ Upstream commit 4e351f4087 ]

The GPI DMA controller is only responsible for QUP peripherals, and
cannot work as a general-purpose DMA accelerator.

Set DMA_PRIVATE capability for it.

This fixes error messages about GPI being shown when an async-tx
consumer is loaded.

Fixes: 5d0c3533a1 ("dmaengine: qcom: Add GPI dma driver")
