[PATCH v1 12/45] clk: mediatek: mt8365: Convert to mtk_clk_simple_{probe,remove}()

AngeloGioacchino Del Regno
2023-02-06T15:30:50Z

Change the custom mt8365_simple_gate to be mtk_gate clocks and
audio clocks to be composites to be consistent with all of the
other MediaTek clock drivers, allowing to convert this entire
driver to use the common mtk_clk_simple_probe() mechanism that
also allows building this driver as module.

While at it, also perform some macro compression cleanups and
switch to use module_platform_driver().
