MT8512 declares a separate U_BOOT_DRIVER, probe() function and compatible
table for the topckgen and infracfg clock gate controllers, despite both
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. Both controllers share the same DM flags and (absent)
bind() callback and are merged into a single U_BOOT_DRIVER.

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

No functional change intended.
