ARM: dma-mapping: remove custom consistent dma region
This patch changes dma-mapping subsystem to use generic vmalloc areas for all consistent dma allocations. This increases the total size limit of the consistent allocations and removes platform hacks and a lot of duplicated code. Atomic allocations are served from special pool preallocated on boot, because vmalloc areas cannot be reliably created in atomic context.
