Helge Deller e522a12e48 parisc: Improve cache flushing for PCXL in arch_sync_dma_for_cpu()
[ Upstream commit 59fa12646d9f56c842b4d5b6418ed77af625c588 ]

Add comment in arch_sync_dma_for_device() and handle the direction flag in
arch_sync_dma_for_cpu().

When receiving data from the device (DMA_FROM_DEVICE) unconditionally
purge the data cache in arch_sync_dma_for_cpu().
