[PATCH 9/9] clk: mediatek: mt8512: convert to mtk_gate_clk_data

MT8512 currently declares a separate U_BOOT_DRIVER, mtk_clk_tree,
probe() function and compatible table for each clock gate controller,
despite all of them sharing the same implementation.

Convert MT8512 to use the generic mtk_gate_clk_data infrastructure.
This allows the topckgen-cg and infracfg clock gate controllers to
share a single generic driver.

No functional change intended.
