Subject: [PATCH 1/3] arch: unicore32: ksyms: export additional find_first_*()
 to avoid compiling failure

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

The related error (with allmodconfig under unicore32):

    MODPOST 4039 modules
  ERROR: "find_first_bit" [sound/soc/codecs/snd-soc-uda1380.ko] undefined!
  ERROR: "find_first_zero_bit" [net/sctp/sctp.ko] undefined!
  ...
