Subject: [PATCH] ARM: 6202/1: Do not ARM_DMA_MEM_BUFFERABLE on RealView boards
 with L210/L220

RealView boards with certain revisions of the L210/L220 cache controller
may have issues (hardware deadlock) with the mandatory barriers (DSB
followed by an L2 cache sync) when ARM_DMA_MEM_BUFFERABLE is enabled.
The patch disables ARM_DMA_MEM_BUFFERABLE for these boards.
