        src/common/lib/libc/arch/arm/atomic: atomic_nand_16.S atomic_nand_32.S
            atomic_nand_64.S atomic_nand_8.S sync_fetch_and_nand_8.S

Log Message:
Use gcc 4.4 and later operation for nand, i.e.
*ptr = ~(tmp & value) instead of *ptr = ~tmp & value

There was also another bug in sync_fetch_and_nand_8 which I've also fixed.

PR port-arm32/50513: Incorrect logic for atomic_nand_xx.S
