    xen/common: Guard freeze/thaw_domains functions with CONFIG_SYSTEM_SUSPEND
    
    This patch adds CONFIG_SYSTEM_SUSPEND guards around freeze_domains
    and thaw_domains functions.
    
    This ensures they are only compiled into the hypervisor when the system
    suspend functionality is enabled, aligning their inclusion with their
    specific use case.
    
    This addresses two Misra Rule 2.1 violations.
