clk: mediatek: mt8189: use driver data to store the clock tree

Pass each controller's struct mtk_clk_tree through the driver data and use
the generic probe function for all the MT8189 clock drivers, instead of a
dedicated probe per controller.

The apmixedsys, topckgen and vlpckgen controllers keep their own
U_BOOT_DRIVER since they rely on dedicated ops and on the parent bind()
callback, but they now get their tree from the compatible data, like the
clock gate controllers.

No functional change intended.
