[PATCH v2 22/32] clk: mediatek: mt8518: use driver data to store the clock tree

[Julien Stephan]

Pass each controller's struct mtk_clk_tree through the driver data and use
the generic probe function for all the MT8518 clock drivers, instead of a
dedicated probe per controller.

The apmixedsys and topckgen 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.

No functional change intended.
