[PATCH v2 11/32] clk: mediatek: mt7986: deduplicate clock gate drivers

[Julien Stephan]

Describe the ethsys gates directly in a struct mtk_clk_tree, reference the
tree from the driver data and use the generic mtk_clk_topckgen_ops instead
of the dedicated clock gate ops.

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

No functional change intended.
