[PATCH v4 0/5] clk drivers: Terminate clk_div_table with sentinel element

I noticed that some of the clk_div_tables in different drivers are not
terminated with a sentinel element. This may cause the code in
clk-divider.c to read garbage that happens to be beyond the end.

This patchset fixed all instances of this bug that I could find, except
for a case in drivers/phy/ti/phy-j721e-wiz.c that is already fixed in
linux-next:
  https://lore.kernel.org/lkml/20220117110108.4117-1-kishon@ti.com/

In this version of the patchset, I addressed Philippe Mathieu-Daudé's
style comments. As far as I found it reasonable, I simply updated the
existing patches, but in the case of the Actions Semiconductor drivers,
I made a bigger cleanup in a separate patch.


v4:
- Various style fixes

v3:
- Change the Actions patch according to Mani's comment

v2:
- Add Fixes tags
