[NET] smc91x: fix PXA DMA support code
The PXA DMA support code for smc91x doesn't pass a struct device to the dma_*map_single() functions, which leads to an oops in the dma bounce code. We have a struct device which was used to probe the SMC chip. Use it. (This patch is slightly larger because it requires struct smc_local to move into the header file.)
