[U-Boot] [PATCH 1/3] ARM: remove unused bit operations

[Daniel Mack]

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.
