These architectures don't need relocation fixups, so reduce their
codesize a bit by defining CONFIG_RELOC_FIXUP_WORKS.

Also remove the reloc_off field from their global data structures
as it is no longer needed.

Note that the location of the standalone application jump table pointer
in the global data structure is affected by this change, breaking
execution of standalone applications compiled for previous versions of
U-Boot. We will therefore increment XF_VERSION in the next commit,
which also touches this area.

We have common defines that we duplicate in various ways.  Having an
arch specific config.h gives us a common location for those defines.

Eventually we should be able to replace this when we have proper
Kconfig support.
