dma-debug: move initialization to common code
Most mainstream architectures are using 65536 entries, so lets stick to that. If someone is really desperate to override it that can still be done through <asm/dma-mapping.h>, but I'd rather see a really good rationale for that. dma_debug_init is now called as a core_initcall, which for many architectures means much earlier, and provides dma-debug functionality earlier in the boot process. This should be safe as it only relies on the memory allocator already being available.
