[ARM] 5034/1: fix arm{925,926,940,946} dma_flush_range() in WT mode

The CPU's dma_flush_range() operation needs to clean+invalidate the
given memory area if the cache is in writeback mode, or do just the
invalidate part if the cache is in writethrough mode, but the current
proc-arm{925,926,940,946} (incorrectly) do a cache clean in the
latter case.  This patch fixes that.
