net: hisilicon: Fix dma_map_single failed on arm64
[ Upstream commit 96a50c0d907ac8f5c3d6b051031a19eb8a2b53e3 ]
On the arm64 platform, executing "ifconfig eth0 up" will fail,
returning "ifconfig: SIOCSIFFLAGS: Input/output error."
ndev->dev is not initialized, dma_map_single->get_dma_ops->
dummy_dma_ops->__dummy_map_page will return DMA_ERROR_CODE
directly, so when we use dma_map_single, the first parameter
is to use the device of platform_device.
