[PATCH] media: mtk-vcodec: remove allocated dma_parms

[Hsin-Yi Wang]

9495b7e92f71 ("driver core: platform: Initialize dma_parms for platform
devices") included dma_parms in platform_device. There's no need to
allocate again.

Fixes: 13483fc2f20f0e2db7ba9c39b095ac7ea46f8de8 ("media: mtk-vcodec: set dma 
max segment size")
