core: rename atomic_clear to atomic_clear_bits
Change the name of atomic_clear to atomic_clear_bits to make to name more clear - the function clears only selected bits, but the name may suggest that it clears the whole variable. It is done as a part of porting to Zephyr, where atomic_clear zeros the variable.
