Subject: dma-mapping: make map_benchmark compile into module
Under some scenarios, it is necessary to compile map_benchmark into a
module to test iommu, so this patch changes Kconfig and export_symbol to
implement map_benchmark compiled into module.
On the other hand, map_benchmark is a driver, which is supposed to be able
to run as a module.
