[NET] smc91x: prepare SMC_USE_PXA_DMA to be specified in platform data
Now that the original SMC_USE_PXA_DMA specific code will always being built if CONFIG_ARCH_PXA is defined, so to make this part of the code to be PXA public, and still prevent it from being built if support of PXA is not selected. A SMC91X_USE_DMA flag is added to the platform data to allow platform to choose its usage of DMA. Note this flag itself is so named to be generic enough (assuming other platforms can also use DMA). It keeps backward compatibility to set the SMC91X_USE_DMA flag if SMC_USE_PXA_DMA is still defined.
