[v1,00/25] MediaTek clocks cleanups and improvements

  This series performs cleanups and improvements on MediaTek clock
drivers, greatly reducing code duplication (hence also reducing
kernel size).

There would be a lot to say about it, but summarizing:

* Propagates struct device where possible in order to introduce the
  possibility of using Runtime PM on clock drivers as needed,
  possibly enhancing reliability of some platforms (obviously, this
  will do nothing unless power-domains are added to devicetree);

* Cleans up some duplicated clock(s) registration attempt(s): on
  some platforms the 26M fixed factor clock is registered early,
  but then upon platform_driver probe, an attempt to re-register
  that clock was performed;

* Removes some early clock registration where possible, moving
  everything to platform_driver clock probe;

* Breaks down the big MT8173 clock driver in multiple ones, as it's
  already done with the others, cleans it up and adds possibility
  possibility to compile non-boot-critical clock drivers (for 8173)
  as modules;

* Extends the common mtk_clk_simple_probe() function to be able to
  register multiple MediaTek clock types;

* Removes duplicated [...]_probe functions from multiple MediaTek SoC
  clock drivers, migrating almost everything to the common functions
  mtk_clk_simple_probe();

* Adds a .remove() callback, pointing to the common mtk_clk_simple_remove()
  function to all clock drivers that were migrated to the common probe;

* Some more spare cleanups here and there.

All of this was manually tested on various Chromebooks (with different MTK
SoCs) and no regression was detected.

Cheers!
