[PATCH v6 17/27] clk: mediatek: pllfh: clear state data in mtk_clk_cleanup_pllfhs

Currently, fhctl_parse_dt function sets some state variables that are
never cleared in the unregister nominal path or register error one.
As they are stored in a static array variable, given as parameter from
the caller function, they retain their values until they are initialized
again by another fhctl_parse_dt call.

So, add a loop to clear these state variables in mtk_clk_cleanup_pllfhs
function.
