Some modules need find_first_bit() and find_first_zero_bit(), so export
them.

After check the code, 'bswapsi2' and 'muldi3' are useless for
unicore32, so can remove them to avoid compiling failure.

This patch includes some generic stuff including elf and ksyms.
Because all one-line asm-generic headers are auto-generated by ASM_GENERIC_HEADERS
in arch/unicore32/Makefile, so the rest seems very little.
ELF handling functions and module handling functions are also here.
