    clk: mediatek: pllfh: Don't log error for missing fhctl node
    
    [ Upstream commit bb7b3c8e7180f36de75cdea200ab7127f93f58cc ]
    
    Support for fhctl clocks in apmixedsys was introduced at a later point
    and to this moment only one mt6795 based platform has a fhctl DT node
    present. Therefore the fhctl support in apmixedsys should be seen as
    optional and not cause an error when it is missing.
    
    Change the message's log level to warning. The warning level is chosen
    so that it will still alert the fact that fhctl support might be
    unintentionally missing, but without implying that this is necessarily
    an issue.
    
    Even if the FHCTL DT nodes are added to all current platforms moving
    forward, since those changes won't be backported, this ensures stable
    kernel releases won't have live with this error.
