dts/hisilicon: hi6220: Remove dma-coherent from gpu dts node
The question is that if we use coherent_swiotlb_dma_ops by adding a
"dma-coherent;" property to GPU's dts node GPU will not work properly many
kernel error msg: Mali: Executor GP: Job 2106 Timeout on Mali_GP. But if we
use noncoherent_swiotlb_dma_ops GPU will work normally. And Debian release
can work well with both coherent/noncoherent_swiotlb_dma_ops. The only
difference is that debian allocates dma bufs with cma not ION.
This commit seems to be a workaround and have no idea about the reason yet.
It seems that coherent_swiotlb_dma_ops may not work well with ION.
Will disscuss with ION guys.
