[PATCH 00/32] clk: mediatek: Migrate to common probe/remove helpers and fix memory leaks

[Akari Tsuyukusa]

This series migrates most MediaTek clock drivers to the common
probe/remove helpers provided by the MTK clock framework.

Key changes:
- Fix memory leaks on module removal caused by missing
  platform_set_drvdata() calls (patches 1-6).
- Add missing MODULE_DEVICE_TABLE() (patches 7, 8).
- Add missing support for cpumux, PLL, pllfh, and sub-device
  auto-population to the common helpers (patches 9-12).
- Convert all compatible clock drivers to use struct mtk_clk_desc
  and mtk_clk_simple_probe/remove (patches 13-32).

The memory leak and MODULE_DEVICE_TABLE() fixes are split from the
migration patches to allow backporting to stable.

Drivers not converted:
- MT6765 apmixedsys: requires direct register init.
- MT6795 apmixedsys: uses mtk_clk_register_ref2usb_tx().
- MT7629 eth/sgmiisys: uses a hacked probe sequence (multi-instance
  sgmii gates).
- MT8173 apmixedsys: uses mtk_clk_register_ref2usb_tx() and custom
  divider registration.
- MT8188/MT8195 topckgen: call devm_clk_hw_register_mux() and register
  a notifier.
- MT8196 vlpckgen: requires direct register init.
- MT8365 apmixedsys: uses devm_clk_hw_register_gate().
