[PATCH] blackfin: optimize ffz, __ffs, ffs, __fls, and fls functions

From: Zhaoxiu Zeng blackfin has popcount instruction (ONES), we can do the efficient computing (ffz, __ffs, ffs, __fls, and fls) use this instruction. Adapted from "https://en.wikipedia.org/wiki/Find_first_set; and arch/ia64/include/asm/bitops.h. Signed-off-by: Zhaoxiu
