    xen/arm: Reorder SCI resource cleanup in domain destruction
    
    Move the SCI (System Control and Management Interface) resource cleanup
    earlier in the domain_relinquish_resources() sequence to ensure proper
    cleanup ordering during domain destruction.
    
    The SCI cleanup is now performed before TEE (Trusted Execution Environment)
    cleanup rather than after P2M mapping cleanup. This reordering ensures that
    SCI resources are properly released before other subsystems that might
    depend on them are torn down.
    
    This change addresses potential resource cleanup dependencies where SCI
    resources need to be released before P2M mappings are cleaned up, preventing
    potential issues during domain destruction on ARM platforms with SCI 
support.
    
    Fixes: e2cc10867b63 ("xen/arm: add generic SCI subsystem")
