common/board_f: introduce arch_setup_dest_addr()
In order to move ppc-specific code out of setup_dest_addr(), provide an
arch-specific variant arch_setup_dest_addr(), that can be used by
architecture code to fix up the initial reloc address.
It is called at the end of setup_dest_addr() initcall and the default
implementation is a nop stub.
