1. arch: arm: Fix cxd56xx for SMP …

   Summary:
   - In apache#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.
