Introduce bus_get_bus_tag() method
Provide bus_get_bus_tag() for sparc64, powerpc, arm, arm64 and mips nexus and its children in order to return a platform specific default tag. This is required to ensure generic correctness of the bus_space tag. It is especially needed for arches where child bus tag does not match the parent bus tag. This solves the problem with ppc architecture where the PCI bus tag differs from parent bus tag which is big-endian.
