arch: arm: Fix cxd56xx for SMP
Summary:
- In https://github.com/apache/nuttx/pull/14465,
atomic_compare_exchange_weak_explicit() was newly introduced
in semaphore. However, cxd56xx has an issue with the API
if SMP is enabled (see up_testset2 in cxd56_testset.c).
- This commit fixes the issue by using LIBC_ARCH_ATOMIC.
Impact:
- Only cxd56xx SoCs in SMP mode.
Testing:
- Tested with spresense:smp, spresense:wifi_smp
- NOTE: If DEBUG_ASSERTIONS is enabled assert would be happend.
I think this might be another issue.
