ARM: change dma_alloc/free_coherent to match other architectures
As a lot drivers currently rely on the 1:1 virt->phys mapping on ARM we define DMA_ADDRESS_BROKEN to mark them. In order to use them on other architectures with a different mapping they need proper fixing. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
