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.
