By adding asm-generic/io.h support, there are some duplicated function implementation, like phys_to_virt, memset_io, memcpy_(from|to)io. Let's remove them to use the default version in asm-neneric/io.h. Meanwhile move isa_bus_to_virt() down below <asm-generic/io.h> including line to fix the compiling error of missing phys_to_virt definition.
