There's no need to keep pointers to the ELF sections available while
the module is loaded - we only need the section pointers while we're
finding and registering the unwind tables, which can all be done during
the finalize stage of loading.

Without these, exit functions cannot be stack-traced, so to speak.
This implies that module unloads that perform allocations (don't
laugh) will cause noisy warnings on the console when kmemleak is
enabled, as it presumes that all code's call chains are traceable.
Similarly, BUGs and WARN_ONs will give additional console spam.

The various sections are all dealt with similarly, so factor out
that common behaviour. (Incorporating Peter Huewe's fix.)

This patch adds ELF section parsing for the unwinding tables in loadable
modules together with the PREL31 relocation symbol resolving.

Move platform independent header files to arch/arm/include/asm, leaving
those in asm/arch* and asm/plat* alone.
