unicore32: fix build error for find bitops

Remove the __uc32_ prefix in find bitops functions.
Move find_* macros behind asm-generic/bitops.h inclusion.
see commit <19de85ef574c3a2182e3ccad9581805052f14946>
  bitops: add #ifndef for each of find bitops
also see commit <63e424c84429903c92a0f1e9654c31ccaf6694d0>
  arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT}
