    x86: provide consistent cbmem_top() for CONFIG_LATE_CBMEM_INIT
    
    For x86 systems employing CONFIG_LATE_CBMEM_INIT, set_top_of_ram() is
    called in ramstage to note the upper address of the 32-bit address
    space. This in turn is consumed by cbmem. However, in this scenario
    cbmem_top() cannot always be relied upon because get_top_of_ram()
    doesn't return the same value provided to set_top_of_ram().
    To fix the inconsistency in ramstage save the value passed in
    to set_top_of_ram() and defer to it as the return value for
    cbmem_top().
