ath79: ag71xx: pass correct device pointer to dma functions
linux 4.19 doesn't accept a NULL device for these functions. It also complains that the device struct in net_device doesn't have a dma_mask set. Pass the device struct from platform_device for these functions. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
