Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC

When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support.  However, other recent changes led to a different
implementation (ELF relocation), where this no longer works.  By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.

So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.
