efi: Unify DMI setup code over the arm/arm64, ia64 and x86 architectures

Browse Source 
All architectures (arm/arm64, ia64 and x86) do the same here, so unify
the code.

Note: We do not need to call dump_stack_set_arch_desc() in case of
!dmi_available. Both strings, dmi_ids_string and dump_stack_arch_
desc_str are initialized zero and thus nothing would change.
