asm-generic: fix ffs -Wshadow warning
gcc -Wshadow warns about the ffs() definition that has the same name as the global ffs() built-in: include/asm-generic/bitops/builtin-ffs.h:13:28: warning: declaration of 'ffs' shadows a built-in function [-Wshadow] This is annoying because 'make W=2' warns every time this header gets included. Change it to use a #define instead, making callers directly reference the builtin. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
