powerpc:Add support of SPL non-relocation
Current SPL code base has BSS section placed after reset_vector. This means
they have to relocate to use the global variables. This put an implicit
requirement of having SPL size = Memory/2.
To avoid relocation:
- Move bss_section within SPL range
- Modify relocate_code()
