* fix CLI section links in the Summary
* fix heading in Pointing Device doc
* fix headings in PS/2 Mouse Support doc
* add explicit section ids to I2C Master Driver doc
* reformat GPIO Controls table
Much like the I2C Master Driver doc, I found this a bit less than ideal to read. (The table was actually wider than the space available for it.)
Reformatted so each GPIO function is an H3 heading, followed by a paragraph and a table of each architecture's old-style function.
* migrate changes from I2C Master Driver doc to Japanese translation
* add explicit anchors to I2C Master Driver docs
* fix code block language markers
The language markers are case-sensitive; using the wrong case means the syntax highlighting doesn't work.
Good: ```c
Bad: ```C
* restore Japanese I2C Master Driver doc to current master
Can't update the internal tracking references accurately until the changes to the English doc are committed to master.
* add explicit anchors to edited files
* change ChibiOS/ARM to ARM/ChibiOS
Because ARM/ATSAM is also a thing that exists.
* fix code block language markers again
Used the wrong markers in a few spots. Also these are apparently always supposed to be lowercase.
* add section anchors to cli.md
* restore table formatting on GPIO Control doc
* remove changes to _summary.md
