Subject: [PATCH v6 00/54] MediaTek clocks: full module build and cleanups

Changes in v6:
 - Changed order in Makefile for some clock files: specifically,
   apmixedsys goes always first, then topckgen, then anything else.
   This fixes MT8186 issues and also slightly optimizes the clock
   registration sequence, as apmixedsys and topckgen are registering
   root clocks used by all other modules.
 - MT8186 now works again!

Changes in v5:
 - Fixed typo in MODULE_DEVICE_TABLE() for clk-mt8195-vpp0/vpp1

Changes in v4:
 - Rebased over clk-next branch as of 21/02/2023
 - MT8135: Squashed removal of __initconst annotation with conversion
   to platform drivers as suggested by Chen-Yu
 - MT8135: Added mention of the introduction of the dummy clock in
   the commit description of patch [54/54]
 - Fixed Kconfig ordering issue for MT8195 IMGSYS dependant option

Changes in v3:
 - Added conversion to simple_probe for MT8135 clocks
 - Reordered added Kconfig options for MT8195, MT8186
 - Additional config options for MT8195, MT8186 are now default
   enabled if parent COMMON_CLK_MT81{95,86} is enabled
 - Added .remove() callback to MT2712 and MT7622 apmixedsys drivers
   to avoid resource leakage on unbind/removal
 - Dropped unwanted and useless change on mt7629-eth.c

Changes in v2:
 - Fixed issues on MT8183 (thanks Chen-Yu!)
 - Changed builtin_platform_driver() -> module_platform_driver() for
   MT8167 vdecsys clocks (as that was a mistake!)
 - Some patches were split, some others were reordered
 - Summarized: applied changes from Chen-Yu's review

This is part 2 of the "MediaTek clocks cleanups and improvements" series,
which was already picked.

If reading this full cover letter is too boring for you, here's a short
summary of the changes of this series:
 - Added mtk_clk_pdev_probe() for mtk-mmsys probed clocks;
 - Added divider clock support to common probe mechanism;
 - Various cleanups here and there;
 - Converted most clock drivers to platform_driver;
 - MediaTek clocks can now be built as modules.

NOTE: Applies on top of [1] and [2].


Full blurb:

This huge series adds more cleanups on top, reducing size and adding more
commonization for clock drivers probe/remove, which also includes a new
common probe mechanism for multimedia clock drivers that are usually
probed by mtk-mmsys instead of a dt clock node: thanks to this, it was
finally possible to convert almost all clock drivers to the common probe
mechanism, which *finally again* makes us able to build all these drivers
as modules!

Since this looked like being *the* way forward, I went on converting some
more drivers away from OF_CLK_DECLARE_DRIVER to full platform_driver(s),
allowing for more (actually, almost all!) drivers to be built as modules.

While at it, I also added some more consistency in macros usage by
removing all of the duplicated full macro declaration for MediaTek gate
clocks and replacing all of those with using the GATE_MTK macro instead,
producing a nice reduction in amount of lines per file but, more
importantly, improving readability and eventual future batch changes.

This amount of commonization will also, in my opinion, greatly improve
the review process for new clock drivers, as they will be mostly just a
list of clocks and won't contain much new code, as it's all going to be
handled in the common places, which also reduces chances to see new clock
driver related bugs emerging on one SoC or the other.

Since I don't own devices with all of the supported MediaTek SoCs, I
could not test some of the conversions on real hardware... but I am
confident that this will work as the drivers are *very* similar on a
per-generation basis.

This series was build-tested for all (both module and built-in build)
and was manually tested on MT6795, MT8173, MT8192, MT8195.
