clk: mediatek: mt7988: deduplicate clock gate drivers

MT7988 declares a separate U_BOOT_DRIVER, probe() function and compatible
table for each clock gate controller, despite all of them sharing the same
implementation.

Describe the gates directly in each controller's struct mtk_clk_tree,
reference the trees from the driver data and use the generic
mtk_clk_topckgen_ops. The two sgmiisys controllers, which share the same DM
flags and (absent) bind() callback, are merged into a single U_BOOT_DRIVER;
ethdma and ethwarp keep their own drivers since they bind reset controllers
at different offsets.

This also stops using mtk_common_clk_gate_init() and struct mtk_cg_priv,
which are scheduled for removal.

No functional change intended.
