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} Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Cc: Akinobu Mita <akinobu.mita@gmail.com> Acked-by: Akinobu Mita <akinobu.mita@gmail.com> Cc: Arnd Bergmann <arnd@arndb.de>
