asm-generic: change little-endian bitops to take any pointer types
This makes the little-endian bitops take any pointer types by changing the prototypes and adding casts in the preprocessor macros. That would seem to at least make all the filesystem code happier, and they can continue to do just something like #define ext2_set_bit __test_and_set_bit_le (or whatever the exact sequence ends up being).
