davinci_emac: fix for running with dcache enabled DaVinci EMAC is present on TI AM35xx SoCs (ARMv7) which run with D-Cache enabled by default. So we have to take care and flush/invalidate the cache before/after the DMA operations. Please note that the receive buffer alignment to 32 byte boundary comes from the old driver version I don't know if it is really needed or alignment to cache line size is enough.
