Subject: [PATCH] drm/msm: Drop local dma_parms
Since commit 9495b7e92f71 ("driver core: platform: Initialize dma_parms
for platform devices"), struct platform_device already provides a
dma_parms structure, so we can save allocating another one.
Also the DMA segment size is simply a size, not a bitmask.
