Subject: [PATCH v2 0/4] clk: amlogic: drop clk_regmap tables

This patchset removes the needs for clk_regmap tables in each clock
controller driver. Those were used to populate regmap with in the regmap
based clocks.

This saves memory and ease maintenance a bit.

This is the 1st step in a series of rework of Amlogic clocks, to clean-up,
increase code re-use and ease future maintenance.

Changes in v2:
- Add clk_hw_get_of_node and kunit tests for the new helpers
- Split patch adding the .init() and the dropping the table
- Drop devres based solution and something temporary but simple
  while a more generic solution to hook controller init is discussed.
- Link to v1: https://lore.kernel.org/r/20241220-amlogic-clk-drop-clk-regmap-tables-v1-0-96dd657cbfbd@baylibre.com
