[PATCH 10/31] serial: mtk: add support for using dynamic baud clock souce

The baud clock on some platform may change due to assigned-clock-parent set in DT. In current flow the baud clock is only retrieved during probe stage. If the parent of the source clock changes after probe stage, the setbrg will set wrong baudrate. To get the right clock rate, this patch records t
