swiotlb: change swiotlb_bus_to[phys,virt] prototypes
Add a hwdev argument that is needed on some architectures in order to access a per-device offset that is taken into account when producing a physical address (also needed to get from bus address to virtual address because the physical address is an intermediate step). Also make swiotlb_bus_to_virt weak so architectures can override it.
