Remove include/asm-arm/bitops.h a bunch of 'external' marked functions from include/asm-arm/bitops.h. They are not implemented anywhere in the sources, so this forward declaration is wrong.
Also remove the functions __set_bit, __clear_bit, __change_bit, __test_and_set_bit, __test_and_clear_bit and __test_and_change_bit.
All these functions can be implemented in a generic fashion which will be done in the next patch.
