ARM: add relocation support

!! This breaks support for all arm boards !!

To compile in old style, you must define
CONFIG_SYS_ARM_WITHOUT_RELOC or you can compile
with "CONFIG_SYS_ARM_WITHOUT_RELOC=1 ./MAKEALL board"

!! This define will be removed soon, so convert your
board to use relocation support

Portions of this work were supported by funding from
the CE Linux Forum.
