[PATCH] clk: mediatek: pllfh: Don't log error for missing fhctl node

[Stephen Boyd]

Quoting Nícolas F. R. A. Prado (2024-03-08 12:29:56)
> 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.
> 
> Fixes: d7964de8a8ea ("clk: mediatek: Add new clock driver to handle FHCTL hardware")
