ARM/dma-mapping: const a pointer to bus_type in arm_iommu_create_mapping()
Change the function arm_iommu_create_mapping() to take a pointer to a
const bus_type as the function does not modify the variable the pointer
points to at all, and the driver core bus functions it calls all expect
a const * type.
