    clkdom_dump(): improve output text
    
    If the call to clknode_get_freq() returns an error (unlikely), report
    this, rather than printing the error code as the clock frequency.
    
    If the clock has no parent (e.g. a fixed reference clock), print "none"
    rather than "(NULL)(-1)". This is a more human-legible presentation of the
    same information.
