microblaze: drop CONFIG_NEEDS_MANUAL_RELOC

Microblaze and m68k are the only remaining architectures that still enable
CONFIG_NEEDS_MANUAL_RELOC by default.

Microblaze has had runtime relocation support using CONFIG_STATIC_RELA for
quite some time, since commit d58c007498 ("microblaze: Add support for run
time relocation"). Drop support for CONFIG_NEEDS_MANUAL_RELOC and make
runtime relocation the default, as the rest of the architectures do.
