[ARM] Rename consistent_sync() as dma_cache_maint()
consistent_sync() is used to handle the cache maintainence issues with DMA operations. Since we've now removed the misuse of this function from the two MTD drivers, rename it to prevent future mis-use. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
