commit 88b9bd396d5a1f83c49fa1b28745fd7feaca2b2e

    target: cortex-m: fix support for armv8m caches
    
    Scan-build is unable to correctly follow the deferred loading of
    queued read, finalized by the atomic write, thus it incorrectly
    claims that the arrays d_u_ccsidr[] and i_ccsidr[] could carry
    not initialized values:
    
            armv7m_cache.c:154:31: warning: 1st function call argument
            is an uninitialized value [core.CallAndMessage]
               cache->arch[cl].d_u_size = decode_ccsidr(d_u_ccsidr[cl]);
    
            armv7m_cache.c:172:29: warning: 1st function call argument
            is an uninitialized value [core.CallAndMessage]
               cache->arch[cl].i_size = decode_ccsidr(i_ccsidr[cl]);
    
    Initialize the arrays to zero to hide these false positive.
